Girls, can you tell me how to prepare the cervix for childbirth? Tomorrow is 40 weeks and they're going to put me in the maternity ward under observation (I have Rh-negative blood, and my husband has a planned delivery). The baby's head is low, and the cervix is not ready at all. Has anyone experienced something like this? How did your deliveries go?
