Soy Isoflavones - advice pls

Hi all,

Just jumping on in case anyone is searching for soy isoflavones and ttc.

I took them last cycle cd 2-6, started on 160mg for days 2,3 and 4 and upped to 200 for days 5 and 6.

It was the only thing I did different this month and got my BFP on 8DPO after not even a hint of a line for 7 months after a CP. I’m now 4 weeks 5 days pregnant. Could be a coincidence but thought I’d add my experience.

Hello

Just an update here;
Last month I took soy Isoflavones day 1-5.
I ovulated day 16.
My luteal phase was 13 days

This month I did not take soy Isoflavones.
I ovulated day 17
My luteal phase was 14 days.

Overall the months I have taken them vs the months I haven't have made no difference so I won't take them again going forward.

Please don't take soy. I've taken them two cycles - both cycles I got pregnant and I experienced early loss on both.

I also have irregular long cycles. I think soy helps you ovulate but it also messes up the balance of hormones which increases risk of early loss.

Personally - I have 36 to 60+ day cycles. I induced a bleed using progesterone pill and then withdrawing it. I took soy for 5 days. On day 20 I ovulated. 11 dpo I got a positive. By 5 weeks I was bleeding and lost it. Same thing happened on the second round, though I took the maximum and ovulated later, still miscarried around 5 weeks.

I have had another pregnancy before these without soy, which was healthy.

Hello

I'm cd12 here. Taking SI again this month, I dunno why, just to see what happens I guess! Not "trying" this month or next because I wouldn't have wanted my birthday to be in December or January haha.

I don't count AF as luteal phase as that is "day 1" I think??
I had really bad spotting last cycle for about 4 days before AF arrived.

@chutney1 congratulations!! Wishing you all the very best xx

I am back to cd 3.
Had bright red spotting 10dpo then brownish discharge every now and then til 14dpo when my period started. No idea if soy Isoflavones are doing anything positive for me at all.

Currently trying to decide if we might have a couple of months off. I wouldn't like to have my birthday at Xmas or January!

@JS5 oh great I'm glad you got your rise!
This is my first cycle on soys, 10th cycle since my last miscarriage, after trying for 5 months to get pregnant that time. So it's been a while but not ridiculously long. I hope this one sticks too!
I have got quite a few bits planned the next few weeks so I'm hoping that it goes by fairly quickly and no dramas.

fingers crossed for you this TWW!

hi everyone - my positive line has stayed with me and gotten stronger. I'm testing like a mad woman every morning first thing, watching out in case it gets weak as thats what happened with my miscarriage last year. fingers crossed it sticks!
I've been using progesterone cream since i ovulated, and I'm also taking 100mg B6. As I've had two miscarriages before, I've got an early scan at 6 weeks and will get prescribed progesterone then as long as it's a viable pregnancy. I'm so hopeful, and quite anxious!

@JS5 I really feel for you, i found that using the OPKs mega stressed me out, I had to give them up last year after a few months because it was making me obsessive and taking all the joy out of sex a bit. i had a very short, sharp rise which i could easily miss and then worry about it non stop. I usually try to do it every other day from the end of my period onwards until I get ovulation pain, as that takes the pressure off the ovulation week and makes it a bit less exhausting. do you get ovulation pain or any other signs?

@itsLKtoday i think the theory of the soys is that they increase your estrogen to make you ovulate stronger/sooner and then the more mature egg is supposed to produce more progesterone?! but i could be wrong about that, i think i read it on a forum somewhere not necessarily medical advice!

Hi all.

I'm 4dpo and playing the game "I'm not even all that bothered, I'm happy with my lot" which will last another few days before I start frantically symptom checking and googling implantation bleeding 🤪

I didn't used to suffer pms symptoms at all but in the last year have had terrible nausea and sore boobs and spotting for up to 4 days before AF.
I had very few symptoms with my first two other than absolutely disgust at milk and chicken on the bone which wasn't helped as I worked with testers for rancid milk (long story 😅) but did have implantation bleed at around 14dpo (I guess, I wasn't testing) with both.

I don't think that soy Isoflavones have an influence on luteal phase or progesterone as we take them in the follicular phase which all about estrogen.
I believe I've solved (more or less) spotting with vitamin c and b + Angus Castus at least helping reduce symptoms which may be due to increasing progesterone.

i have a vvvfl on a cheapy today at 9dpo 😬
not sure if it's a real one or sticky one so i'll keep you updated for those trying the soys!

@chutney1 the first cycle of 32 days I Od late on CD20 so had a 12 day Luteal.
The second cycle using soy just gone now I Od CD 15 and had an 11 day Luteal (I just rechecked Flo) 26 days total.
before this depending on Cycle I would generally O around CD 14/15/16

@TTCbaby1soph ah that's interesting - did you ovulate sooner than normal with them on both cycles?

@chutney1 it seems it lengthened my Luteal phase to 32 days from 25-26 the first month but this cycle using them back to 25 day cycle. I think I’m going to give them a break this month and see what my cycle does by itself. Didn’t have much time to dtd as dp was away

I've got friends coming over this Friday for dinner so I'll test before that, as if it's negative I'll have a glass of wine (or two!)
usually my luteal phase is only 10-11 days, so my period would start by Friday anyway, but I'm hoping the soys will have made it longer, and maybe not until Monday - fingers crossed!
Knowing me, I'll probably cave and get tempted to test tomorrow/Thursday!

@JS5 hopefully it starts soon! do you usually get any ovulation signs?
I wish i had taken OPKs!
I'm 8dpo now and have really sore massive boobs! this is typical for me during pms though. I always thought this was a sign of low progesterone, but I've been using a progesterone cream this cycle and took the soys so maybe not?! it's hard to tell sometimes, when i look things up it says that everything can cause pretty much every symptom so it's a bit of a guessing game!

Did you get any side effects from the soys?

hi everyone, just got back from a week away.
the soy isoflavones brought my ovulation forward to day 14 this month (usually day 17!) so that's a good sign - still waiting to see if it will lengthen my luteal phase too.
I can't be 100% sure as i only went by ovulation pain, as i forgot to take OPKs on my holiday (woops!) but i think it was day 14 or day 15. i'll let you know what happens to the luteal phase!
I'm pretty sure I'm out this month as i've started PMS already, similar to the usual sore boobs etc, but it's good to see the ovulation change!

Hi Ladies, I’m not banking on the month as I said above I didn’t get that much chance to dtd during fertile window. I’m about ten days past O today so if anything I’m just hoping it lengthens my Luteal phase like last month. I’m close to just giving it all up completely now and just leaving it up to God.
strangely though at 7dpo after sex I was so convinced I was coming on my period as had same cramps and a streak of pink in CM on wiping during the day, not sure what that could be. I usually get a little bit of CM I’ve noticed the day before AF. Anywho I would love to hear some good news on this thread soon!
