Hi can you help answer a question my cousin is in her third pregnancy approx 12 weeks and has just started heavy bleeding with cramps a scan has shown that the sac is coming away from the uterus but the baby still has a strong heartbeat they have told her they do not know which way the pregnancy will go and that she has to go back for a scan in a week. the bleeding has now stopped what are the chances of this being a normal pregnancy ???????/
