Aiyoh, first-time mum worries, I understand! Subchorionic hematoma memang scary when you see bleeding, tapi ramai mums I know dapat jugak and baby turned out fine, it's basically blood pooling between the placenta and uterus, not at the baby itself. Best you check with your OB quickly lang, sebab dia kena monitor it properly through scans and make sure everything okay, especially kalau ada continuous bleeding. Jangan stress sangat first, but definitely get it checked properly!
