Have any of you ever had an under active thyroid and didn’t find out until closer to your second trimester?? I’m freaking out I’ve been on levothyroxine since my last pregnancy that ended last year in nov. due to miscarriage. Well I’m currently 12w2d & my recent thyroid screening came back underactive again, when a few months ago while I wasn’t pregnant, it had regulated itself to normal. Now it’s underactive again it has been I’m guessing since I’ve gotten pregnant again & I’m starting to get anxiety and stress about thinking birth defects I need some advice please I’m freaking out
