Aiyo, thyroid condition memang perlu monitor closely during pregnancy, so best you check with your doctor or OB sebab ada few things doktor perlu tengok, hormone levels, medications you're on, semua tu affect baby nanti. A few of my mum friends ada thyroid juga, and they all managed fine during pregnancy when they followed their doc's advice closely, so jangan worry too much lah, most babies lahir healthy. Which type of thyroid condition do you have? That also makes a difference in what precautions you need. Hang in there, first pregnancy memang banyak worries, tapi kita boleh manage!
