I accidentally take 2 hemarate FA in a day.

It’s understandable to feel worried, but taking 2 Hemarate FA capsules in one day isn’t likely to harm your baby. Yes, iron supplements are important, but taking an extra dose by mistake, especially just once, usually won’t cause any major issues. Just monitor yourself, and if ever you feel any discomfort, let your doctor know. At the end of the day, you'll be fine, don’t stress too much.
