I wonder if anyone can help me. I have just had my second miscarriage at 11 weeks pregnant. The first one was at 9 weeks, which I attributed to my thyroid as my TSH was 3.12 at 6 weeks gestation. I started Levo, but I think this was too late as this was only started at 7 weeks gestation. After the miscarriage, I continued on the Levo and the TSH went right down but the FT4 remained at 12-14 max (range: 9-23 pmol/L). After the miscarriage, I became progressively more unwell with hair loss despite the Levo and I required several short syacthen tests for reduced cortisol production which showed reduced production. I was never started on cortisone as the adrenal function gradually improved, however my GP and Endo here in the UK could not offer an explanation as to why I continued to feel like death and wanted to sleep all day, saying my bloods on Levo were fine.
In desperation, I visited a functional medicine specialist in the US in late 2015, who advised NDT (NatureThroid). This has helped me tremendously, and just after my most recent miscarriage a month ago, TSH was at < 0.01 (range 0.3-4.2 mIU/L
), FT4 at 12.6 (range: 9-23 pmol/L
) and FT3 at 4.9 (range: 2.5-5.7 pmol/L). My FT3 was 5.6 at conception.
I am keen to try to get pregnant again asap, but don't want my thyroid to be the underlying cause and risk another miscarriage. I understand that TSH is often suppressed with NDT and that FT4 is reduced due to the FT3, but my question is: why did my FT4 not go up even with just T4 treatment (Levo) even though the TSH went down? Should FT4 be raied to sustain a healthy pregnancy?
Any ideas gratefully received- I am at my wits end trying to work things out!
Thanks so much in advance
