I got pregnant via IVF...I had spotting around 10th week of pregnancy after a dose of progesterone injection it was gone after that I don't have any spotting or bleeding...now I am 28 weeks 2 days I had heavy bleeding with clots..I immediately went to hospital they have done a scan and the baby was fine..my cervix as well closed...they put me on injection and tablets to stop the bleeding after 2 days the bleeding has stopped and baby movements as well fine.. What's the reason for bleeding..I don't have placenta previa and I asked about the placental abruption but she said that it will cause pain..I am very much worrying...can anyone explain why..
