I'm 41 weeks with my first pregnancy and my baby's head is not engaged. I had a stretch/sweep today and aftetwards the midwife mentioned the risk of umbilical cord prolapse. She explained that if my waters broke and I could feel anything in my vagina I should call 999 and get on my hands/knees with my bottom in the air. I'm now feeling quite worried about how likely this is & whether I'll know or not if the cord has slipped down. Does anyone have any experience/advice that they could share? Thanks!
