Giving Birth Videos
The uterus is essentially a balloon shaped elastic bag. The stiff cervix is the knot of the balloon. Toward the end of pregnancy and in early labor the uterus prepares for birth.
Normally a VBAC is not recommended if you've had three or more previous cesarean, if you had a previous rupture or if you previously had a classical scar which is a vertical incision on your uterus.
