Ask the doctor to strip your membrane. Its a natural way to induce you. Took a day and a half to work in my first pregnancy.
Its not just the sex but the seman that helps I've herd
I think it has to do with something in the sperm that helps you dilate.
Semen softens your cervix. It is orgasm that can get contractions started (same muscles)
I've also read that stimulating your nipples can start labor? Which you can do yourself. Just an idea, not sure if it's true, but what's the harm lol
Nipple stimulation has been very successful in getting things going, but you have to so it for a few hours I believe. It releases oxytocin, which gets your cervix going. Sex and masturbation and any good cuddly happy feelings also release oxytocin, but the nipple thing seems to so it more.
Maybe I'll try the nipple stimulation...even if it doesn't help ..at least it'll feel good lol.
Semen helps to soften the cervix because it contains prostaglandin. Nipple stimulation and orgasms can cause contractions because it causes your body to release oxytocin.
