Before I started a IVF-COH cycle in April last year, my tsh read 6.33(2nd gen), t3&t4 normal. I was put on levo 25mcg every other day. The cycle failed and I took myself off levo coz the thyroid dr gave me the option of taking or leaving the meds at 6.33.
In Dec last year,my tsh read 16.1(3rd gen),ft3 normal&ft4 a little low at 0.64(0.93-? range).(I read COH cycles are extremely stressful for thyroid). I was put on 25mcg daily.
In Mar this year, my tsh read 3.22(3rd gen),ft3&4 normal. Continued same dose.I followed an IVF-FET cycle in April which failed.
Last month, same dose, my tsh(2nd gen) tested at 3.194.A new endo increased my dose to 37.5mcg.
Yesterday(a mth later), I tested at 2.27(3rd gen). I am planning on starting another IVF-FET in a few days, and I am concerned its not enough esp.with all the estrogen I will be taking for the cycle.
I would like your opinion about the following:
From start of cycle or even from now, is it ok if I increased my dose to 50mcg twice or thrice a week, and rest same dose(37.5)?
will implementing increased dose on commencement of cycle a good idea? I go for transfer 2 weeks later,so wish for levels to be stabilized by then.Is 2 weeks enough for levels to stabilize?
Are readings higher on 3rd gen tsh tests than 2nd gen ones?
My ivf dr useless at this, my endo im yet to see, I would really like some opinions since I am a little skeptical about the endo as well.
