I had my membranes swept yesterday at my 39 week appointment as she was doing it she said she could feel my amniotic sac and behind there she could feel my daughter head pushing against the sac . I was 2 CM wrote she did it and she told me she can only go to 2.5 because if she did any further she would end up rupturing my sac . My question is . If I'm still at 2.5 by my 40TH week check up, can she do another sweep? Or would that still rupture  the sac?
