Alamak, I understand you're worried! First thing, please follow up with your doctor for that repeat blood test and discuss the results properly with them, okay? They need to see your full picture and guide you on what's best for you and baby. Hyperthyroid during pregnancy is something doctors manage quite carefully, so don't panic. A few of my mum friends went through similar scares with thyroid stuff during pregnancy, and with proper monitoring it turned out fine. Your doctor asking about symptoms before pregnancy is actually good, they're trying to figure out if this is new or pre-existing, which matters for the next steps. Right now, just go for that repeat test, be honest with your doctor about all symptoms (even the palpitations), and ask them directly if you need medication or just monitoring. Don't Google too much lah, let your doctor explain what's happening in your case specifically. You're doing the right thing by getting checked!
