To strip the membranes your cervix must already be dilated. It can have some effect to trigger labor. Most doctors prefer to induce by 41 weeks or certainly by 42 weeks to avoid the complications of postterm pregnancy.
A membrane sweep increases the likelihood that labour will start within 48 hours. It has a higher chance of working if your cervix is already softening and preparing for labour. It does not increase the risk of infection to either you or your baby.f this isn't your first baby, then you should be offered a membrane sweep at your 41 week prenatal appointment, if you haven't already gone into labour by then. Membrane sweeping is done by your midwife or doctor. While internally examining you, she will simply sweep a finger around your cervix (neck of your womb).
