About 6 years ago I was tested for hypothyroidism due to feeling really fatigued all the time. They found I have subclinical hypothyroidism which means my TSH was high but my T4 was normal. I also tested positive for thyroglobulin antibodies (it was 18) but negative for peroxidase antibodies. I started levothyroxine and have been taking it ever since. I didn’t know to ask any further questions at time, but they never mentioned if I had hashimotos or anything else.
Fast forward to last year I started IVF and as part of the fertility work up, they tested my antibodies again and now they were both normal. I went back to my PCP to tell her there were no more antibodies and she seemed confused. Has anyone had this happen and what does this mean? I still have not been told I have hashimoto or anything other than subclinical.
I just got pregnant for the first time and I’m 6 weeks. I have adjusted my levothyroxine and at 4 weeks, my blood test TSH was at 1.6.
I am so terrified of a miscarriage or anything detrimental. Someone please explain this!

thank you for this info! My doctor never mentioned anything about Hashimoto so I guess I don’t have it?? How often do you get your TSH checked during pregnancy? And do you check your T3 and/or T4 regularly as well?

I did IVF and working with a reproductive endo so they are pretty on top of things. So yours went up even within 1 week from 4weeks pregnant to 5 weeks pregnant? I just had mine checked at 4 weeks with my hcg test and it came back 1.6. I don’t think they will test it again until 8 weeks. Should I get it done before then? I’m currently at 6 weeks.

also does it make a difference that my thyroglobulin was positive but peroxidase was negative? Everything I see on google talks about positive peroxidase.

thank you sooo much for this info!! I was feeling so confident about this pregnancy until today I hit 6 weeks and I don’t know if it’s the emotional side effects of pregnancy but I all the sudden got major anxiety about something going wrong and just couldn’t stop thinking about the thyroid issue! So basically regardless of antibodies or not, if you’re managing with properly medication, your risk of miscarriage and other preterm complications goes down? That’s all I need to know to reassure myself!

you made me feel so much better, thank you so much!!! 💗 Goodluck with the rest of your pregnancy!
