I am looking for anyone whos had a healthy pregnancy with a low tsh.
I was diagnosed hypo about 5 years ago. I had such bad fatigue at the time I was mostly bed bound.
My results back then were free t4 7, tsh 11. Im not sure what my t3 was.
I was put on 100mcg levothyroxine and did feel an improvement but still suffered with bad fatigue and was.diagnosed with m.e
Then about a year ago I saw a different endo who suggested trying t3 as well. It helped enormously but I was very sensitive to it and we eventually settled on a dose of 75mcg t4 once a day and 2.5mcg t3 three times a day. I felt the best I had foryears. Not perfect but much better.
We started trying to concieve and fell right away. At 6 weeks the scan showed a healthy heartbeat.
Also at 6 weeks my endo stopped my t3 and increased my t4. My bloods were normal but he said t3 was too unstable to manage in pregnancy so its better just to have t4. I was not happy as I knowthe t3 would leave my system within daya but the t4 would take weeks to have effect so basically he was reducing my dose, til the t4 kicked in.
A few weeks later I miscarried and the scan showed the baby stopped growing around 7 weeks.
Could be unrelated. Anyway my lovely endo referred me to his professor saying he had more experience in pregnancy.
I went back on my original dose but when I saw the prof was told my tsh was way too low 0.02 so I had to reduce my dose, even though my free t4 was only 12 and t3 was 5.5. I was very cross as I know takimg t3 can supress tsh but did as I was.told. Reduced to 75t4 daily and 2.5 t3 twice daily.
I went on to have another miscarriage a few months later.
I was told my tsh was still way too low (still 0.02!) and it was possibly not helping the pregnancies. I asked if there was any link between low tsh and miscarriage and the prof said no but it was the only thing he could think of!
I tried cuttimg out the t3 but was so ill that its not an option.
So I am now on 50mcg t4 a day and 2.5 t3 twice a day and feel it isnot enough. I am having bloods done in dec (after beimg on this dose for three months) and not trying to.concieve til my dose is stable. Also having other miscarriage tests.
But really want to know if anyone has had a healthy pregnancy with a low tsh? As iI dont think it is the cause of my problems.
Thanks so much in.advance, any info on thyroid and pregnancy welcome!
