TTC and subclinical hypothyroidism

Hi all

I'm 34, and my husband and I have been TTC our first baby since January. We've had no luck yet, but realise it's still quite early days.

However, I recently had a blood test after an ultrasound found a polycystic ovary. This came back negative for PCOS, but showed my thyroid function was out of whack. My TSH is 4.93, higher than the reference range, and my free T4 is on the lower (but normal) side at 14.7. So my GP told me I'm subclinically hypothyroid.

Not really knowing anything about thyroid issues, I asked what this meant for fertility and pregnancy. The GP said some fertility specialists like TSH to be under 2.5 when TTC, but it's more about optimising the body for conception than anything else. They didn't suggest medication right now, but said if I'm still not pregnant within the next 2-3 months they'd repeat the tests (with an extra check for thyroid antibodies/Hashimoto's disease) and refer me to the fertility clinic for advice if my TSH is still high. But if I do become pregnant, nothing further needs to be done.

I've since done my research and it doesn't seem to tally with what the GP said. As I understand it, for a healthy baby and pregnancy TSH levels should be below 2.5 and T4 ideally on the higher end of the normal range. And the NICE guidelines seem to suggest we should delay TTC
until I'm medicated and my levels have normalised and stabilised: cks.nice.org.uk/topics/hypothyroidism/management/preconception-or-pregnant/

I'm not sure how far I'll get with the GP, as they admitted they're not totally clued up on these matters. So I've ordered an advanced thyroid self-test kit to get a full picture of what's going on. I'm then thinking about seeing a specialist privately for advice on whether I should be taking thyroxine or not.

For anyone who's been through similar, my questions are:

  1. What sort of specialist would be best to see? An endocrinologist or fertility specialist/reproductive endocrinologist?
  1. Once on medication, how long did it take to get your thyroid hormones to the right level for TTC and pregnancy?
  1. Do you have any suggestions or advice? I'm feeling rather unsure and overwhelmed by the whole thing.

Thanks so much in advance. :)

Before I had my baby my thyroid was at the higher end of the tsh range 6/7. I've always watched it as hypothyroidism runs in my family. Doctor would never prescribe me Levo even though symptomatic, even went private to see and endo and he said until my tsh is higher he wouldn't prescribe levo either. Fortunately I managed to get pregnant pretty quickly but after the birth that's when my tsh shot up. I did use the ovulation sticks when TTC and found them really useful as I didn't always follow the same period cycle.

ChinChilly · 15/10/2024 11:16

@Leadingwithloveandkindness mine was a very similar number, 4.4 I think. My GP wouldn’t have any of it as it was within ‘normal’ I was having multiple miscarriages, in the end a recurrent miscarriage clinic prescribed me levothyroxin as it wasn’t normal for pregnancy or TTC. They prescribed it whilst I was at the early stages of pregnancy and went on to have a happy healthy baby. Unfortunately GPs don’t seem to move from what is ‘normal’ to optimum for TTC.

My GP surgery did get a stern letter from the miscarriage clinic telling them they needed to continue monitoring my TSH levels throughout any pregnancy’s and in general, and in fairness they do call me every 6 months for a blood test

Leadingwithloveandkindness · 15/10/2024 09:14

It’s 4.5 which I definitely appreciate is within a normal range but is much higher than the recommended 2.5

Huge thank you to everyone who’s contributed to this thread. I found it incredibly helpful in trying to understand whether the doctors are correct who keep telling me my thyroid issues aren’t anything to worry about! We are having a really difficult journey to having our second child and paid privately to have some tests done and the only thing which seems to be a red flag is the thyroid issues - I have elevated TSH and antibodies. Would anyone be able to pm or email me the details of the London private endocrinology consultant mentioned? My GP won’t prescribe levothroyoxine unless I have an endocrinology consultant recommendation.

What's your TSH? Mine was 70 and antibodies and gp could prescribe levothyroxine, didn't even hesitate.

So happy for you @Jellybelly888! Knowledge is power! GP awareness of hypothyroidism, optimum TSH and its impact of fertility is pretty poor unfortunately. Push for an endocrinologist referral through pregnancy if you can. They should be keeping your TSH below 2.5. Wishing you all the best!

Thank you so much, I’m still in shock! I knew thyroxine works fast but not this fast! Also, how quickly did you all up your doses when you got BFP? I am terrified at having a MC. I’m only on 25mg so going with the 30% more rule people have used on this thread, I should maybe have an extra 25mg twice per week I think. Just until I get some advice from my GP and insist she speaks to an endo. Gosh all so complicated isn’t it and annoys me so much that there will be couples out there being broken hearted over something that might be easily fixed!

I know this thread is old but it’s been my saving grace and been such a help that I wanted to give my story too. After a year of TTC and a TSH level between 8.5 and 5.6 depending on when in my cycle I was tested, I went armed with all this information that I learnt on this thread to my GP. She reluctantly prescribed me 25mg of levothyroxine and the first month on it we got a BFP! It’s still early days but I just wanted to put this on here to encourage ladies that they know their own bodies and to do that you know and feel is right. Don’t stop until you feel you’ve been listened to.

What a lovely thread to read the updates of! I'm also pregnant with our first, over 2 years since first posting on here! A few bumps in the road along the way, but we've made it to 21 weeks so far with this little one ❤
@Owl86 I'm delighted for you! 💙
@Songbird50 congrats 🥰 not far too far behind me!
@CTMcG @rathernotshare congrats on your little ones! 😊 I hope all goes well in your new pregnancy @CTMcG!

bookworm100 · 05/07/2023 21:53

Hi @Owl86 - I've just spent the last half an hour reading the entirety of this thread and am so pleased it worked out for you! I'm at the beginning of my journey with this and am currently going through the mill with GPS...I'm based in London/SE, could you please let me know the name of your endo specialist?

CTMcG · 05/07/2023 20:42

@Owl86 ahhh so happy to hear this! Congratulations 🥰

Owl86 · 05/07/2023 20:36

Goodness me, I can't believe it was over 2 years ago that I started this thread! I'm delighted to read these happy updates - congratulations to you all. 😊

To add another good news story, I now have a 9 week old baby boy who was conceived naturally after nearly 2 years trying. We'll never really know why it suddenly happened after so long, but the positive pregnancy test did seem to coincide with my thyroid levels finally stabilising on levothyroxine.

Really pleased the thread has been helpful, and I hope it continues to be so.

I just got notification on this thread after posting nearly over 2 years ago too! I now have a 14month old and am currently 6+3 weeks with my 2nd! I am on 100mg of levothyroxine and so far so good! Hope everyone is well! X

rathernotshare · 05/07/2023 15:39

I just got a notification on this thread as I had commented 2 years ago, well I now have a 1 year old! Took us 2 years to conceive. Never did get thyroid meds, but have recently had another check and awaiting results. Fingers crossed it will be sorted if we try for another.

Songbird50 · 05/07/2023 12:25

Hello all,

I hope that all of the recent deliveries/pregnancies have gone/are going really well and we have a growing gang of little ones on this thread. The thread and you girls helped me so much, so I just wanted to update you and anyone else who happens to read this thread in the future looking for hope/ advice that I am now 14 weeks pregnant naturally with my first, a little girl, and all is going well so far. My latest tsh is 0.31 and I have a consultant appointment in a couple of weeks just to monitor my thyroid. To those who are ttc my advice is keep at it, don't lose faith, I know just how hard that is, and keep investigating, I had a lot of trial and error with hormone tests, cycle tracking and supplements, quite apart from dealing with my thyroid. It took over 2 years; as well as being hypothyroid, I'm also now 41 with an amh of only 0.07pmol/l or 0.01ng/ml, a previous blighted ovum, and a cycle that was getting very irregular and disappearing for months at a time. It is possible. Best wishes to all of you.

Un7breakable · 01/05/2023 17:42

Thanks @winningeasy . Not comfortable lying but will retest fasting and with a morning test and take it from there.

winningeasy · 01/05/2023 17:19

TSH must be tested first thing in the morning, and must be fasted. Just water.

It's likely a lot higher than that. As the day progresses it reduces.

winningeasy · 01/05/2023 17:17

@Un7breakable yes defo try to get it. But it's unlikely your GP will prescribe. I would suggest booking an appointment with a private fertility practice and say you have been trying longer than you have and you are considering IVF but want to get a fertility MOT first, get them to test TSH (they likely will anyway) and everything else, then when they come back with elevated TSH, say you have read it needs to be under 2 and can you give me a letter to take to my doctor to get a prescription. Your doctor should prescribe it with a letter like this and with the view that IVF is
on the cards / your age. Then say you want to wait a couple of months regulate your TSH before you go down ivf path. This hopefully you will get pregnant.

This is what I did, and twice I was pregnant with 1-2 months. Then you will need to stay on the dose throughout your pregnancy and ideally for first couple of months of post partum.

I had a similar level to you. 20 weeks pregnant with DC2.

Good luck!

Un7breakable · 01/05/2023 16:46

Should also add I get heavy periods and my TSH was tested at night after eating which I've read might have an impact.

Un7breakable · 01/05/2023 16:18

Bit of an old thread but seems like you ladies know your stuff. I'm 35, TTC since the start of the year with no luck. Have issues with spotting, some tiredness and am that person always under blankets or in a down jacket. Did a mail order thyroid test and got a reading of 2.88. have ordered another for a month's time. Already under GP for spotting. Assuming the 2nd test comes back with a similar level do you think the GP will do anything or will they think I'm mad?

Thanks for the messages @Ojejku and @Owl86 - i have reached out to a private endocrinologist this morning and will also do my best to speak to NHS doc asap although it's proving near impossible.

I have some spare Levo so have started taking it

I was prescribed 50mg before x

Good luck!

I am really scared them that my dose is too small ☹️ should be on 50mg but my doctor gave me only 25 for now as I am only starting. I really hope he will agree to increase it after first blood test if needed 😔

Hi @winningeasy, congratulations on your pregnancy! 😊

TSH should be below 2 or 2.5 in the first trimester. Mine was 0.1 when I got pregnant (I was on levothyroxine) but it suddenly shot up to 4.6 at around 8 weeks. So I ended up doubling my dose on the advice of both my private endocrinologist and an NHS consultant obstetrician. My TSH has been very stable since (around 1.3) and I'm now 25 weeks.

I'd definitely try and speak to your doctor about it. Failing that, your midwife at your booking appointment should be able to help - but I'm assuming that appointment won't be for a few weeks yet?

Advice needed ladies!

Do you know what is a normal non-medicated TSH for pregnancy? Does it go up? What is the safe / unsafe level?

I am kind of shitting it. Bit of a backstory, I have slightly elevated TSH, around 3/4ish, so subclinical. It took us ages to get pregnant with our first child. After persuading a doc to prescribe Levo, I got pregnant the first month taking it.
Then was on it for the remainder of my pregnancy.
We started trying ages a couple of months ago, and was following a nutritional plan from a nutritionist specialising in thyroid issues, was getting 2.5ish levels without Levo, so have stayed off of it. Have just found out I am pregnant again, obv great, and then have had levels tested and TSH is 4.36. I am so worried this is going to cause me to miscarry, do I need to be demanding they re prescribe Levo? My doctors are bad, it's so hard to get hold of someone and get a proper appointment. I constantly have to re explain quite a complicated situation.

I am eating so healthy, regulating my blood sugar, improving micro biome, reducing inflammation.... so there's not much more I can do personally to bring it down.

Any help and advice appreciated!

Hi! Maybe you should seek advice from private doctor if your GP refuses to prescribe levo? I think TSH should be below 3 if you are pregnant as it goes up during pregnancy

May I ask what was your dosage when you felt pregnant for the first time? I have subclinical hypothyroidism with TSH around 5 and finally got prescription for levo but my starting dose is 0.25 and I am worried it won't make any difference 🙄
