Pregancy with Hypothyroidism

[Rose96]

Hello! Im 6 weeks pregnant wirh my rainbow baby after having a loss at 18 weeks.

Before I knew I was pregnant I had some blood done just to check everything was back to normal after my missed miscarriage. By the time I got around to the bloods I was already pregnant but my results came back with TSH level of 34 and T4 on 8.4.

I've just started levothyroxine 75mg but I'm so worried. I'm panicked that im going to either cause a miscarriage or cause the baby to be harmed with my levels being so high. I know I'm under the right care and its been found so early on but just looking for people who have had under active thryoid and e everything was OK

I had no problems with my thyroids pre miscarriage which is why this has surprised me. I feel some of the symptoms can easily be dismissed for other things

Thanks

I got diagnosed with underactive thyroid after birth of my oldest child. Then went onto have 2 other children, whilst taking the meds. No problem whatsoever. You are only taking what your body is not producing naturally.

The medication is to bring your levels of thyroxine up to normal and reduce your level of TSH. This is preferable to not being treated.

I developed hashimotos after the birth of our second child. I didn’t have any more (our choice) so can’t comment on that part sorry, but I’m sure that having this issue identified can only be a positive thing for you.

I have an under active thyroid and was diagnosed some years before I had my children. It does increase the risk of miscarriage but only if untreated.

Does your doctor know you are pregnant? Generally your dose of thyroxine needs to increase slightly, but it may be different as you have only just started the medication.

Your midwife will do extra blood tests as your pregnancy progresses. I think it may mean that your care will be said to be consultant led (both my successful pregnancies were because of interactive thyroid I think for the first and then that plus age for the second). However, I never saw a consultant (midwife might have consulted them) and it didn’t affect my birth plans.

once you have given birth your thyroxine dose is likely to need to go down slightly.

Yes my Dr's started the dose, but my midwife said now they will take control of the doses. I'm under a consultant and bereavement midwife due my loss so I know I'm under the right care this early on

Just pregancy after loss is alot and now this to worry about too 😞

Hopefully you will be monitored closely now. My levels were under during my second pregnancy, but I was (horrifyingly) told that they would probably normalise after pregnancy and not given thyroxine. My TSH was 8.3, I was totally exhausted. All was fine with my baby, thankfully, but I should have been given thyroxine, it was a few years after she was born before I got treated.
Make sure they keep an eye on your levels with regular bloods, have they tested you for antibodies?

Hi.
so sorry to read of your loss.
before I got pregnant my TSH was 13 and I was on 75mg, which I upped myself to 100mg when trying to conceive as I’d read that optimum TSH for conception is under 2.5 or 3 I think.

at 8 weeks I had a blood test and mine was 3.3 so I now take 150mg as advised by my midwife and GP.

just keep pushing for blood tests but I’m sure now you’re medicated all will be fine.

Hello :)

I have hypothyroidism and was terrified when I first got pregnant that my levels were too high, as I had read you have to start monitoring them straight away. My dr didn’t take it seriously and it took me about 7 or 8 weeks to get her to actually blood test me, and yep they were way too high. Got put on a higher dose and everything is now controlled, everything is fine with the baby!

Something I found reassuring was being told by a midwife that the reason your levels are suddenly much higher is because your baby is taking all your TSH, causing an imbalance in your body, not your baby’s. So for the first weeks, until your baby establishes their own production of TSH, your body will prioritise sending them all of yours.

Of course if this is left, it can cause problems for you but it sounds like you’re on top of things and it will be brought under control soon ❤️
