Hi , I had spotting and bleeding during my pregnancy too. Same thing I went to KKH O&G, baby heartbeat was normal. Dr only advice me to rest more. I ever had 2 miscarriages before. My advice is don't think too much. I know its not easy but its important to keep clam and happy for a healthy baby :)
I had bleeding 3x during pregnancyfirst was 6 weeks I was told it's threaten abortion. I was given med and jab to stabilised the pregnancy
