Anyone TTC a Girl come talk to be about it!(30 Posts)
I am very lucky to have 3 lovely DS and am "allowed" one more child so I want to raise my chances of having a girl so any tips?
I know I am very lucky to have my boys and would be very happy to welcome another lovely son.
I found it on the fertility Friends website in private sway pink forum lol!
I dont detect any desperation on this thread...? I think anyone thinking of swaying realizes that it is just that. Swaying. Not guaranteeing a particular gender. I dont see any harm in trying to sway the odds. By the way, seatfor5, the info you posted is directly copied from thr InGendersite. Where did you find it hon?
IrnBruTheNoo if you took the time to read the thread rather than just putting your point of view you would have seen that none of us have said we would follow the points in fact quite the opposite!
How do you explain women who conceive girls who do not follow the swaying technique??? Sorry, but you're so desperate to conceive a specific gender you're not seeing that this is all complete BS.
A lot of info there and if you want to stick to all of it it would be very time consuming. I am just doing the practical things to sway, there is no way that DH will be interested in fannying around with his diet, supplements and underwear!
There are 7 Factors that make up swaying: pH, ions, minerals, diet, hormones, supplments and timing. You can't just count on one to work. If you only do timing that is only 1/7th of a sway.
Lots of calcium (milk, yogurt, etc.)
Low salt intake
For the GIRL diet the ranges are:
(salt) Na++ 700-1000 mg
(Potassium) K+ 2,500-3,500 mg
(calcium) Ca 1,200-1,800 mg
(Magnesium) Mg 200-300 mg
Tier One (to be eaten when ever you want)
(Girl diet, acidifying diet, mineral diet and progesterone diet)
Read your labels. And watch your sodium and potassium in foods!
yogurt- Greek style or organic only (read labels and look for yogurts containing NO potassium)
Milk- t (nomral milk has 350mg of potassium and organic has about 250mg of potassium. some brands of UHT milk has O mg)
tahini (sesame seed paste)- look for low salt
Strawberries and Raspberries (look for frozen, unsweetened or canned in syrup although fresh will do)
Sugar free gum (not with truvia or stevia in it)
Tier Two (eat as much as you want as long as you watch minerals and stay within range)
(Girl diet & Mineral Diet)
Parmesan cheese (3 tbs max a day)
Propel fitness water with calcium
eggs (Egg Beaters are best)
cottage cheese- read labels for sodium
low salt bread
pasta- look for calcium fortified pasta
fish (poached in 500 ml of water to reduce sodium)
low sodium mayonnaise
Tier Three (eat once a day)
(Girl diet and Acidifying diet)
Cranberries- dried or raw (NOT Craisens)
corn cereal or puffed rice
lamb- loin or chop
(up to 130g of meat per day- no red meat= testosterone)
Make sure to think about mouth wash and tooth pasts as well as other things you may place in your mouth. Always try to find low to no sodium products
Drink suggestions: Milk, Cranberry, Diet Cool-aid, Aquafina, Dasania (Aquafina and Dasania both are made with reverse osmoses which naturally lowers the pH of water to about a 5-6) and Cranberry Juice.
One of the fastest ways to lower pH that has been discovered is with fake sugars. The best lowest acidic one is Aspartame. It does have some side effects. Some people are allergic to it so they can�t drink it. Others it may cause a headache.. this means to cut back. You can find Aspartame at Walmart in there drink mixed called Great Value sugar free. This has been found to be the best drink mix because it lowers pH the best. If you can not find this then others have found that crystal lite works for them. You should try to drink 66-100 oz of this drink mix every day.
Most of your Cranberry will be taken in pill form. However you can drink the juice as well. You can only drink either pure cranberry juice or it mixed with some other berry.
This is another drink. In the past we thought peppermint tea would lower testosterone, lower or stabilize estrogen and raise progesterone. Newest studies studies suggest that it may raise estrogen or stabilize. Because the effect to estrogen isn't unknown at this time; IG now recommends Saw Palmetto to raise progesterone and lower estrogen and testosterone (see below). But this is gentler; so if you want to use this instead of SP you take 3 cups a day. This is the only tea you can drink for ttc a girl.
When to have sex:
O + 12
This has better success than cut off. Abstain from sex for 7 days or more, and then have sex 12 or so hours after you ovulate. Obviously, you have to pinpoint your ovulation exactly for this:
Ok the reason o+12 works better than shettles is because you have more control of your pH till O. With o+12 you only need to keep pH low for about a day of your attempt (yes you need low pH before but with shettles your pH could spike while sleeping and you would never know)
for O+12 you need opks, a BBT (thermometer), knowledge of your cervical mucus, and cervical position. Also 3 practice cycles with charting of temps, opks, cp and cm would be helpful as well so you know on average when you O.
Ok you will get a +opk.. this means its time to watch your cm and cervix. You cant take opks first thing in the morning because you always have Lh in the morning...
ok so you have +opk.. this means you may o in 8-48 hours. Now start watching your cervix and cm. When you O your cm will be ew (most people not me lol) and your cervix will be really really soft. Don't worry about hight because that fluctuates with bms. 12 hours after you O your cervix will go from soft to hard and your cm will shift from ewcm to creamy or from creamy to dry. If you do not have cm you go by your cervix texture. These 2 usually go hand in hand but if they don't go by cm. You have from now (o+12) to o+20 (8 more hours) to do your attempt.
Keep temping as this is the only way to really confirm O. If you have been charing for 3 months you will know on average when you o because you will have marked on your chart (probably in the notes section) at what time the cm shift occurred then count back 12 hours and you know.
After your attempt you need to keep your pH low!! Douche an hour before (if your pH is 5 or higher or if you have ewcm) and then after your attempt check every 1/2 hour to make sure your pH stays low! If your pH jumps up then do 1-3ml of douche to re-lower it. Some people an hour before do rephresh or replens (depending on pH) an hour before and have found pH will stay low till temp spike. Others find it makes pH go higher. 4 hours after your attempt do a lime tampon and leave it in for 4 hour (thus hitting that o+20 mark). Keep pH 4-4.5 (either with douche, or replens or rephresh) till your temp spikes and you have conformed O.
Have sex least 2-3 days before Ovulating. Then keep your pH low till O.
Most important info!!!
First off, diet is the most imortant sway factor. But no matter if o+12 or cut off (shettles) you need to do this! Hour before your attempt check your cm pH. It needs to be 4-4.5. If not then either douche or use rephresh or replens to lower pH. If you are not doing TBM then you may insert 1-3 ml of lime douche 5 minutes or so after bd. Then 1/2 hour after attempt you need to check pH again. If it is high you need to lower it back down to 4-4.5. Check your pH every 1/2 hour up to 4 hours. Then place in a lime doushe tampon.. and leave in for 4 or more hours. The first 4 hours are critical because it takes 4 hours for x sperm to get to the waiting zone. With cut off you need to keep your pH 4-4.5 till confirmed O so check often!
Girl- conceived in the �new moon� phase
Boy- conceived in the �full moon� phase
Positive ions favor boys Negative ions favor girls. Spring has slightly more - than +, Summer has more - than +, Fall has slightly more + than -,and Winter has more + than -.
Full moon (from the day moon is full till day before new moon) has more + New moon (from the day moon is new till day before full moon) has more -
So if you ttc in winter on a full moon this strongly favors boys. Summer in new moon- strong girl. Spring in full moon is more neural.
NOT EVERYONE IS AFFECTED BY IONS IN THIS WAY! You know if you are by your pH. High pH favors boys and indicate egg is in polarity for y sperm. Low pH favors girls and indicates egg is in polarity for x sperm
No female orgasm
Missionary position for sex
Husband take HOT bath or shower a few minutes before sex (or have a heating pad heat up his �buddies�)
�Jump and Dump�- go to bathroom and �dump� everything right after sex (not for TBM) See this.
Abstinence over 7 days is best or under 48 hours.. not between 2-6 days as this favors boys
Dh wear �tighty whities�
Supplements are to decrease cervical mucus pH. Studies show that low pH favors girl conceptions. The goal of the girl diet is to increase calcium and magnesium in the cm and to change pH; the goal of supplements is to change pH and make creamy CM. Here are all the supplements that I have heard of for ttc a girl. Granted there may be more. They key here is for you to find the right 'recipe' to make low pH with creamy cm with calicum mixed in- this is the goal. Remember.. it is better to take supplements in liquid form if you can find that because it is more easily absorbed by the body...
* Supplements amounts listed here are the maximum amount for dw and dh. This isn't based on weight but more so on safety.
*Calcium citrate (1200 mg combined with diet every day) take from af to af (can stop at O if you want to save money) calcium in the cm helps to sway for a girl (to prevent low ionic strength cal and Mag ratio has to be 2 to 1. If you have a digital pH tester don't worry about this) (not calcium carbonate)
*Magnesium (300 a day combined with diet!)take from af to af (can stop at O if you want to save money) Mag. in the cm helps to sway for a girl
Folic Acid (450 mcg a day)* you can take more of this if needed and be safe!! Take all the time THIS DOES NOT SWAY! IT PREVENTS BIRTHDEFECTS AND PREVENTS MC
*Acidilophis (2 a day) take from af to af (can stop at O to save money) This is taken to lower pH. side effects: this is a funny supplment. Either it will lower your pH dramaticaly or you will raise it. It is different for different people
*B6 (100 mg a day) If taken before O it may delay O. But for those that it doesnt delay o, take all the time, but when you get a bfp you need to ween off slowly- if you take 100 this means the next week you take 80, then the next week 60 then 40, 20, 10 then stop. This is taken to raise progestrone and legthen luteal phase. Side efffects: When taken before O it may dealy O. It will also legthen your luteal phase
*Chasteberry (Vitex) (500 mg a day) this is to regulate cycles- do not take if you have regural cycles.
*Cranberry (total of 1,500 to 10,000 mg fresh fruit equivalent a day if possible. This is based on equal to fresh fruit equivalent.. not amount on bottle. This part can be tricky. So, 10,000 ml equivalent to fresh fruit) take from af to O (stop at O) this is taken to lower pH side effect: cranberry can not be taken after O as it can cause mc. Cranberry is a blood thinner so if you already taking a blood thinner do not take this.
*Lydia Pinkham (take from af to O) this is taken to raise progestrone and regulate cycles side effect: This will either make your cycles regular or screw them up
*Vitamen C- 500 mg -af to af (can stop at O to save money) in pill forum this makes you more acidic. (to much can cause gas and diarrhea)
*Saw Palmetto standardized -320mg a day (thats one pill a day)- Make sure to buy the standardized kind. Take from AF to O.. not to be taken in the 2ww or with pg! This lowers testrone, lowers estrogen and rasies progesterone. Do not take this with Clomid.
*Sudafed (not pe) real drug name is: pseudoephedrine: (a few hours before sex) this is taken to lower pH and dry up cm
*licorice root 450mg 3 times a day- lowers testosterone and raises estrogen (this is good for dh not for dw). Only have him take from your af to O. He needs the 2ww for a break. Can only take for up to 6 months then he needs a 2 week break (have him follow this 2 week break after the 2ww break so he will total a 4 week break).
*Calcium citrate (1200 mg a day) can take from your af to af (or stop at your o to save money) calcium lowers pH in dh and helps x sperm
*Magnesium (300 a day combined with diet!) can take from your af to af (or stop at your o to save money)
*Acidilophis (2 a day) take from af to OThis is taken to lower pH. side effects: this is a funny supplment. Either it will lower your pH dramaticaly or you will raise it. It is different for different people
*Cranberry (total of 1,500 to 10,000 mg a day if possible. This is based on equal to fresh fruit equivalent.. not amount on bottle. This part can be tricky. So, 10,000 ml equivalent to fresh fruit) take from af to O can take from your af to af (or stop at your o to save money) this is taken to lower pH side effect: blood thinner
Optimal pH of cm should be
4-4.5....Optimal pH of dh semen should be 7-7.5 (you can lower this to 4-4.5 with lime once it is outside of dh)
Hot showers for dh and dw (lowers sperm count and lowers pH). Some people are using refresh/replens finger to lower cm pH. They are also useing acidjel (has the best acids in it), vinegar douche (if it doesn't raise your pH), or lime douche. This is all based on an environment theory that an acidc one produces girls.. Also Oing will raise female pH so avoid this .For ttc a girl you should use the following products because they have been found to lower female testosterone (which favors boys) Nail polish remove, Nail polish, and anything with Aerosols.
For dh he needs to wear tight fighting underwear. He also should try to get on the girl diet and he needs to lower his semen pH to a 7-7.5. He must try to gain weight as this for dh sways girl. While you must try to lose weight. He can lower pH with cranberry supplements. His pH can be changed quickly with these- he should take as much needed the day before bd to achieve low pH . Finally, sperm count is highest in the morning so try to time bd at night. New info suggest that you want low blood sugar in the mornign when ttc a girl. So avoid carbs in the morning. Also cardio sways girl while weights sway boys. You should avoid eating till noon, whild dh may have breakfast. Finally, warm things sway girl and cold things boy (effects pH and ions)
The Moon...There is no doubt that the moon can sometimes have and effect on gender if ones body responds to it. Here is the scientific reason behind why this might be and how you can alter that effect if you need to. The theory is that a different sperm have different ions. Now when there is a full moon out it is scientific fact that there are positive ions in the air and we breathe it. When there is a new moon out there are negative ions in the air and you inhaling that as well. The theory is that some peoples bodies react to these ions just like nature does (Google crops and moon, or fish and moon). So when there is a full moon those positive ions cause your egg to have positive ions thus attracting the y sperm. Now if you are O�ing in a full moon you need to try to counteract the effects of the Postive ions. You can do this with running water, air purifires, rock salt deionizers to counteract the effects of a full moon or use magnate therapy using negative ions- polar north, and avoid computers or at least have a fan blowing on you while you are on a computer.
Info on pH strips and retrieving cm...
Digital pH testers are the best for testing pH. Then there are two pH strips you want to look for (if not buying digital). Alkalive (also called pHion) and full range (also called universal). These are found the cheapest on ebay (search pH strips then select lowest to highest price.) Alkalive can measure between numbers like a 4.75 but can be hard to read so you need a back up. The full range strips will only read one number- no between but they are very easy to read.
How to retrieve cm�.TMI!!! You reach up inside your V and with your finger you touch the cervix. Then you hook your finger and pull out. The cm on the tip of your finger is the one you want to test. The cm closest to your cervix is the most alkaline and the cm on the edges of your v is acidic. Wipe this on the pH strip (or on the digital pH tester wand) and wait for up to 10 minutes (no waiting for digital) depending on how much water is in your cm. If your pH strip doesn�t change and you have tried several times to test pH; this means you have low ionic strength in your cm (which means you NEED a digtal pH tester). Urion pH only tells you how you are doing with your diet and supplements that day- it does not help with swaying besides that.
To test dh pH you have him give a sample in a cup or a condom. Then test that sample with pH strips right away (the longer semen sits out the higher the pH goes and you want to know his initial pH).
*helpful tip: If you can not retrieve cm to test pH in this manner get a instead cup or diva cup. Place it in vj for 30 minute-hour. This will fill up with fresh cm that you can test easily.
The Diva cup...The Diva cup will increases your chances of becoming pregnant. And it will not effect pH. But here is the tricky part. Every 1/2 hour after attempt you need to remove the cup and test the pH inside your vj and in the cup and lower if necessary. Then place the up back in. You do this up to 4 hour then take the cup out and put in a lime tampon.
Douche...*Douche needs to be body temp or you may kill sperm.
*To help conceive a baby girl use an acidic Douche...
There are 3 douches you can choose from. 7% vinegar/calcium, lime douche and store bought vinegar douche. 7%is most effecteve due to the acetyl radical and acetic acid then after that is lime and last is store bought. Please note: 7% Vinegar has been known to raise the pH in some women instead of lowering it. So please test this out before your attempt. Lime has not had this problem. The following is an explaion of why it is better and how to make it.
7% vinegar/calcium: (pH of 4)
7% vinegar/cal works for TBM because of 3 reasons: The first is Because the y sperm at low pH's tails freeze (they don't like low pH), the second is because at that low pH calcium binding to sperm occurs and the Third is because of acetyl radical and acetic acid . These chemicals play a big part in girl conceptions. Now onto the new step. When you TBM you freeze the tails of the y sperm to give the x sperm a chance to head up. But according to the study, douching an hour before is Critical for this to work. 1/2 hour the freezing stops and the y sperm start to swim again.
Douching an hour before is Critical for this to work. AT 5 mintues after bd (or 30 mintues after tbm), ake your pH reading. If it is to high then take the douche and insert 1-3 ml into the vJ to lower the pH to 4-4.5 You then check Keep checking this every 30 mintutes for up to 4 hours; then take a lime douche soaked tampon and place it in there to prevent leakage- you can remove this 4 hours later. The following is explanation on how to make the mix, the tampon, and other info. DO NOT USE THIS FOR PLACING DIRECTLY INTO SPERM (TBM). Only lime juice (not the douche) can be used to lower semen pH directly.
How to make 7% vinegar:
This can made in an hour. It is easier to make the 7% by freezing than with boiling.. Here is what to do..Put 5% vinegar in freezer. Watch for when a forms a layer of ice on the top. Then remove that ice (skim it). Do this 4-5 times and the % will be right. Then take it out. it is now 7%. The day of your attempt add the calcium power (or pill if you cant find power) and let it dissolve for one hour. pH should be 4 after you add the calcium. Add 3-4 drops of distiled water (to activate it) and then it is ready to be used.
Lime douche: (pH of 2)...
Mix lime with distilled water - test pH. If it isn't low enough mix more.
Let the solution stand for approximately 10 minutes.
-One hour before intercourse stir the solution again then insert some of the solution into the vagina (This can be done with a douche or a syringe (both available at pharmacies).
-While inserted, empty the douche or syringe slowly and gently preferably while lying down to ensure maximum effect. The hour before you can either use a store bought douche bag or a big syringe (12+ml). Let is run out and wash away ewcm. The 1/2 hour after follow up douches is only 1-3ml. This follow up douches are ment to just lower pH. You do not need to douche an hour before if you have a pH of 4-4.5 and no ewcm.
Lime douche Tampon...
*To make a lime douche tampon you place lime douche in a plastic cup and soak the tampon while still in the plastic applicator. Right before inserting take the tampon out so that it isn�t dripping. Then you insert it while while making sure you dont let any sperm out and leave it in for 4 hours. This is to be done after every attempt. If you are doing a cut off, you need to check your pH every hour till O. This can be tricky at night, so be careful. You dont need to put a lot in, just enough to keep pH low. Always always always make sure your hand are clean. Also remember with tampons you run the risk of TSS. No matter what your plan.. 1/2 hour after BD you should insert follow up douche into your vj and don't let it out This isn't a douche- but rather a mix you insert to freeze the y sperm and to give the x sperm a better chance. Then keep cheking every 1/2 hour up to 4 hours. If you are not doing TBM then you should check your pH 5 mintues after bd and do a lowering douche (1-3ml) if needed. Then keep checking every 30 minutes up to 4 hours. To check the pH after attempt you only check the combined pH at the entrance; not deep inside. But if you have to lower your pH you do need to put it up in there carefully.
Refresh and Replens...
Replens: pH 2.8
Rephresh: pH 4-5
Replens is now used for replens finger. Rephresh is used as a lube.. HOWEVER if your pH is already a pH less than 5 do not use replens, you can use rephresh as a lube when bd as it has the right actic acids for ttc a girl. rephresh has a pH of 5 you want the pH to be 4-4.5. The higher your pH the higher the pH of rephresh will be as it is a reactive lube. where as replens is always a pH of 2 point somthing PLEASE TRY THIS AHEAD OF TIME TO SEE HOW IT EFFECTS YOUR pH!! For some women they will raise pH. For the 1/2 hour after attempt if you want to lower pH with with this you need to use rephresh; not replens.
*Replens finger. This is for women who want to lower pH the days before bd time.. Every other day bd make sure your hands are clean and then you dip your finger in replens or refresh. Then, sit down on the toilet and insert your finger with refresh and pull out. If tested right away your cm should go from high to low (7 to 4-4.5) and stay that way for a long time. . You woud use this every other day to lower your pH.
If you need lube ttc a girl you have two choices. Either Rephresh (please read above) or canola oil. Lubes do not sway well for a girl on there own. You need to do everything else as well. Lube is just to help you bd. Canola oil has a pH of 6.83 but it is an oil can can not sway. You can use canola oil right before your attempt to help you to get pregnant however some women's pH will raise become of this. So you NEED to check pH every 1/2 hour up to 4 hours and lower if necessary.
Bd'ing every day verses abstaining for over 7 days...
Here is the thing. First off do the opposite of what ever you did to get your boys. Did you bd every day? then abstain, did you abstain for over 7 days? then release every day or every other day. Second, only try abstaining of 7 days or more for about 6-12 months. Then if you are not pg get a microscope and check to make sure you dh sperm are alive. A small number (3%) of men can not abstain because there sperm all die. Or if you don't want to use a scope, just switch to bd every day or every other day if you just want to get pg.
Do I think abstaining is the best between the 2? YUP! However, for those 3% who it can't work for I want to make sure they aren't waisting there attempts. If it was up to me I would have everyone who was going to abstain have them check there dh semen the first time they abstain to make sure none of their attempts are waisted.
Are you ready for this - my next post is massive - i have found a private pinkteam forum and here are their "rules"
And if course there's nothing 'daft" about not eating salt, which is very unhealthy. I'm eating very healthily, though it's slightly boring.
vortex you can eat meat of fish once per day, as much rice and pasta as you like as long as you didn't salt it. Corn, lentils, apples, boiled green veg, porridge (good way to consume all that milk), yoghurt, nuts, oil, unsalted butter, herbs and spices. I find it ok when not eating out. I don't fuss too much about what fruit and veg I have, though do avoid bananas, oranges and mushrooms, and I boil instead of steaming. You can have as much sugar as you want, though that's obviously v unhealthy. Be careful with mineral water, especially sparkling. I drink tap, or Evian or such with low sodium when out. good luck!
Don't think anyone is trying to play god GingerJulep...
Don't get your 'joke' either? Is it one of those where you need to be there? <genuinely baffled>
LousyMe, let's talk more about this girl producer you are offering for hire... . Do you only have one model? Is it a nationwide service?
littlemimosa I was joking... just pointing out the really effective means of achieving this after being rather shocked at the number of people trying to 'play god' albeit through daft diets/sticking random substances places they shouldn't etc.
Eh? Theres a full list if allowed and forbidden foods on InGender plus recipes. I warn you though, its very very restrictive and boring. Not to mention unhealthy.
Private IVF with gender selection?
Or just travel abroad to somewhere gender-selection is easier to obtain via abortion?
Have sex with my DH? 4 out of 4 girls. I thought about hiring him out to Posh.
I am going to give this a go but I won't be going to any extremes. From Monday I am taking magnesium, calcium, folic acid and cranberry tablets and will be TTC from July. There is some good info on ingender but some of the contributes are a bit nutty, I have boys and would love to balance the family but isn't the be all and end all.
I will modify my diet, just need a list of allowed foods.
It's completely down to chance. Only have another if you're willing to accept either gender, IMO.
I've thought about this before but it seems a lot of effort(!) - I know someone who swayed for a boy and it worked though.
Hi I also have 3 boys!!! Same feelings on the matter too!
Am already taking magnesium. Roman, you've said what foods to avoid, but what should you eat???
Anyone got a link to douching?
Its amazing what some will go to to sway - They dip tampons in lime and stick them up after DTD, they take Sudafed to try and reduce CM (that seems to help to have a girl), They change their whole diet to try and reduce the bodies PH, They only DTD 12 hours after OV and only the once! and then a lot of them don't understand why they are not PG - I will be taking cranberry tablets and drinking more Cranberry juice and taking a mag supplement but that's it turn s out after all the reading I just want a baby
Lol. As hilarous as that sounds, that is the principle behind lowering the ph of your vagina in order to sway the odds of a girl sperm making it to the egg. InGender has tons of info on lime and vinegar douches.
Ok my unofficial study from a few years ago on here suggest that people who having knicker bleaching issues are more likely to have girls, so you need to somehow make your fanjo acidic, pour vinegar up there or something.
Have a look at the InGender website. It has lots of info on timing and diet to conceive a specific gender. Though timing and diet are just two of the seven 'factors' involved in swaying according to them. It's quite complex but they claim good success rates. By the way, they reckon the Shettles method is not reliable and that the so called 'O+12' method of timing (ie a few hours after ovulation) is better for conceiving a girl. Anyone got any evidence for this? Be interesting to have a mn poll on boy/girl conception timings!
Ok, I'm doing a diet for girl, under med supervision by consultant at respected hospital (not UK). There is science to support it - will have a look for a link for you. The principle is you should increase your magnesium and calcium and reduce your sodium and potassium.
So: don't eat any salt or processed food - no bread, crackers, no soup, cereal, whatever. Look at ingredients carefully as even sweets and ice cream etc often contain salt. Don't eat high potassium foods: bananas, dried fruit, coffee, tomatoes, oranges, peppers. Drink >1 litre of milk per day. Take calcium and magnesium supplements every day.
I am not pg so don't know whether it works for me! Also my job involves a lot of eating in restaurants and a lot of foreign trips where I have little control over what I'm eating, so I don't follow very carefully. But I've changed my levels (at least they were good 2 months ago when I last had them tested).
Doctor says I can adjust my chances from 50-50 to 65-35. So only try it if you will welcome a 4th boy (which I expect is my destiny lol)
