Does it hurt when they break your water?
Does it hurt when my waters break? No, it shouldn’t hurt when your waters break or when they are broken for you. The amniotic sac, which is the part that ‘breaks’ doesn’t have pain receptors, which are the things that cause you to feel pain.
How many cm dilated before they will break your water?
If your cervix has opened up to at least 2-3 centimetres dilated and the baby’s head is well engaged (low down in your pelvis), your waters will be broken (see below under Artifical Rupture of Membranes). If it is not possible to break your waters a second Propess pessary may be inserted if appropriate.
