Unfortunately nothing will really bring on labour unless your body is already ready to give birth
They do say semen and oxytocin probably the most likely thing to naturally induce though! Daily if you can handle it I guess?!
My midwife told me that the gel they use in an induction to bring on labour contains the same stuff that semen does. That's why they recommend sex as a natural way to bring on labour! So if you really want to try for a spontaneous labour, I'd say have it everyday if you can!
As much as possible! Haha when the penis hits the top of the cervix, it releases hormones to get baby moving and also semen helps activate these hormones too!
idk if this is why, but at 37+0 we had morning sex for the first time all week, and that evening my boy was here after zero labour signs 😂
Also, after sex I had a slight bit of blood (pink discharge) is this normal?
