Hi everyone. I’m currently 4weeks today and just got my bfp 2 days ago. I’m wondering if you knowledgeable ladies might help me out about optimum thyroid levels during pregnancy. When I was TTC, we noticed my TSH levels were fluctuating a bit between 1.4-2.8 every few months, so my RE put me on 25mcg levothyroxine because my last value was 2.8 and they wanted to see it below 1.5. I got my BFP 3 weeks after starting my levothyroxine. Just got my beta HCG and thyroid level rechecked and it was 4.1 today with a free T4 of 1.2. My clinic refused to do a free T3 test, they said TSH and free T4 tests would suffice. I would like to educate myself regarding this. I imagine they are going to increase my levo dose from 25mcg to 50 or 100? Do they need to first put me on 50 and then eventually 100 or could they directly go to 100 mcg. ? Any advise ?
