Hey ladies!
Mummawannabe as i understand it the normal TSH of a healthy (non-hypothyroid) woman in the first trimester is about 0.9, and for a hypothyroid woman it's 1.6. ATM there haven't been enough studies done to find out if the TSH has DROPPED due to the pregnancy, or if it is usually lower in these women (unbelieveable i know, but unfortunately more elderly women suffer from hypothyroidism and it's possible that the large-scale studies they HAVE done have been substantially skewed by their relatively higher TSH, which is more common post-menopause...). The Endocrine Society (i printed their PDF) recommend that TSH in women of child-bearing age is kept under 2.5 mainly because from there a 50% doseage adjustment would be sufficient to help keep the woman euthyroid during her pregnancy, whereas if she had TSH of 5, even if the pregnancy was being maintained, it might take a 100% doseage increase to keep her bloods normal-for-pregnancy and she may well suffer from hyperthyroid symptoms from such a massive dose increase.
Anyway, back to me... My GP just called, i've never actually met him, i'm new to his practice, but he's the most senior doctor. He's irish and was very friendly. He told me i was not easy to talk to (in a friendly way, as in "you are challenging me here!") and asked if i was a teacher. LOL! Anyway, he said he is perfectly happy with my bloods in terms of ttc, and that he would have them re-checked when i have the Mirena removed, and has upped me from 50mcgm/day to 75mcgm/day to help with the creeping weight and dead legs. So for now i'm happy :) And i would expect, since my TSH was 2.76, that even that small increase would get me under 2.5 as per endocrine society guidelines.
