Hi all, I'm 17 weeks tomorrow and have a low lying (posterior) placenta. Yesterday I went to a&e and the doctor said I was having a threatened miscarriage after finding fresh blood around my (closed) cervix. The baby had a good heartbeat so all positive signs and the bleeding has stopped. I just wondered if others with a low placenta have experienced similar and also if there's anything you need to do to prevent this from happening? I'm back at hospital this week for a scan and follow up appointment so I'll find out more then too.
