Welcome to HCM,
It is true that hypothyroidism
during first trimester, can adversely affect foetus. Therefore, it is highly recommended that we should do Thyroid function test for all pregnant women in first trimester on their first visit. The safest and most recommended is that women should come for pre- pregnancy counselling
, and we should do this test before they become pregnant.
Your Doctor has done right to initiate your Thyroid medication immediately, but In my opinion, she should have started with 50 microgram once in a day in morning, empty stomach, and gradually can increase the dosage, by regularly monitoring the TSH and T3 levels. By doing this way, we can avoid certain side effects of this medicine. It is not too late. Hopefully your pregnancy will go fine. Just make sure that you take your medicines regularly, and keep on checking Thyroid levels every 4weeks. During pregnancy TSH level
should be less than non pregnant state.
Wish you the best.
