Sayang, please go see your doctor or go to the hospital today for proper check-up, low platelets masa pregnant memang kena monitor closely, so jangan delay! A few of my mum friends had similar situations, and honestly the key is follow through with those weekly checks your doc requested, it helps them track the pattern and make sure everything is safe for you and baby come delivery time. Jangan worry too much yet, tapi don't skip those appointments either, okay? Take care of yourself!
