Hay, this is actually something you really need to talk to your OB about kasi pregnancy thyroid stuff can be tricky, a few of my mum friends had thyroid issues during pregnancy and their doctors adjusted things as they went along, so don't stress too much but do get it checked soon. I know it's worrying kapag nakita mo ang "elevated" sa results, pero sometimes pregnancy itself changes your thyroid levels, and your doctor will know exactly what it means for you specifically. Definitely bring all your test results to your next appointment and ask them to explain what the FT4 level means, they might just want to monitor you or might recommend something, but you'll feel so much better once you know what's really going on. Keep us posted if you're comfortable, I'm sure maraming mums dito who've dealt with thyroid stuff during pregnancy!
