I've just had a long long awaited positive pregnancy test after our second round of IVF. I was found to be borderline hypo last year (TSH 4.9) and have been on 75mg levothyroxine since January which had brought my TSH within normal range.
I've now been told by the hospital to double my Levo dose twice a week due to the pregnancy so I'm taking 150mg on a Wednesday and a Saturday. I've been doing this since last week (am now just 3 weeks pregnant) and feel ok but perhaps ever so slightly hyper, which is fine by me but I want to make sure I do everything I can to reduce the risk of miscarriage or harming the growing embryo. I know the optimum range for TSH in pregnancy is 0.1 to 2.5 but does anyone know what level becomes harmful I.e means you are having too much thyroxine?
Also, what are the optimal ranges for T4 in pregnancy? And again the harmful ranges?
I presume I should get my blood tests done avoiding Wednesday and Saturday for the fairest picture?
My hospital are leaving it to the doctors to monitor me and they aren't very proactive and it's difficult to get more than a TSH so I'm thinking of going to a private endocrinologist to put my mind at ease during these crucial few weeks. Could anyone recommend a specialist in the West Midlands who they have found good to work with?
Apologies for the long post. Any advice gratefully received x
