got Bfp but with untreated thyroid

hello all, I just got Bfp yesterday but after 2WW and been told that i was 4 week 4 days pregnant very happy about it but soon I found out the nurse didn't realise that I had underactive thyroid history, even though before the cycle the routine blood test indicated that my thyroid was 2.9. I had embryo transfer in two weeks ago and yesterday bfp, the clinic told me I am now 4 week 4 days pregnant. I am so anxious now because my thyroid wasn't treated before ET and now 4 week pregnant, has the baby got affected or hurt already, can someone help please😥😥😥 thank you

Your thyroid is in normal range so that is good. Just go to the doctor and ask for your levels to be checked, they may start you on levothyroxine. Did they check your blood when you were there? Congratulations!! Xx

thank you, yes they did lots of blood test at the beginning the cycle but didn't do anything to my thyroid levels at 2.9 should be under 2.5 (I only found out today when i rang them) I just thought they should treat it and only transfer the embryo when the thyroid level in the normal range.

First of all mega congratulations!!! Secondly plz don’t worry!! Mine wasn’t tested and it was way over what is should be but I still got my bfp and Levothyroxine works immediately. Mine was over 4. Something but all is ok so please don’t stress unnecessarily especially as it’s well within normal range xxx

I don’t know because they didn’t test it til after bfp but thyroid levels generally rise a bit in early pregnancy xxx

Hi congratulations on your BFP. Just to try and reassure you,my thyroid is within normal range but is higher than they they like in pregnancy. I went back for another blood test after my BFP to check if it was still high and then only started medication last Saturday when I would have been 5weeks 5days. The clinic didn’t seem worried I wasn’t on the medication straight away xxx

Congratulations! The TSH level for under 2.5 is for optimal levels for conception but you have conceived anyway!! You just need another blood test to see where your levels are now so they can decide if you need treatment or not. Your TSH is not very high so unlikely to do any damage to baby at this stage!! Enjoy being pregnant xxx

Hi babylily. Well done on getting a positive pregnancy test. Try not to worry about your little one, as it is you with th3 problem, not your baby. Obviously, speak to your GP who will check out your thyroid and treat it if necessary. Hope all continues to go well with your pregnancy. Thinking of you. Diane
