I have placenta praevia and my placenta, at the last scan, was covering the cervix by 2.5cm. I had a small bleed at 31 weeks and have spent the remainder of my pregnancy in hospital. I have since had one large, quite scary bleed and 2 smaller ones which have helped to reassure me that I'm in the right place. Im having a c-section tomoro at 37 + 5wks. My only advice would be to listen to whatever the doctors tell her, the big bleed that I had a couple of weeks ago was enough to convince me how dangerous this can be. X
