Alangkah baiknya pergi jumpa doctor lagi untuk confirm sebab bleeding ni, especially since it started with coughing, bisa jadi ada other things going on yang kena check, tak semestinya baby je. Nasib baik scan okay and baby's heartbeat strong, that's a good sign! But bleeding in pregnancy memang kena monitor closely, so follow up dengan doc for peace of mind. A few of my mum friends had bleeding early on and all turned out fine, tapi each case is different, yang penting check dengan doctor regularly. Take it easy for now, rest more, and don't hesitate to go back to A&E kalau ada more bleeding or anything feels off. You're doing the right thing!
