Developed thyroid issues during pregnancy

Audra

13 weeks Saturday and found out a few days I am subclinical hypothyroidism. My T3 and t4 levels are good. My TSH is at 13 and antibodies postive with numbers WAY over. I don’t have any symptoms really. They started me on 50mg levothyrxine and I’ll go to endo. I’m not high risk and they say there is no threat to baby with treatment. Just to monitor and keep under control. Anybody else have this?
