Ok, this is a little graphic and theoretical:
There are many ways to help labour start naturally, but there is no reason to worry, babies come when they are ready. Mine was 3 weeks "over due," waiting is hard on mama, but perfect for baby!
I tried sex (which is proven to work,) but as far as I know that didn't start my labour.
There are three reason that making love will start labour (I think.)
* One is just simply relaxing your body can get it going.
* Another is that your orgasim causes the uterous to contract.
* Another is that there is a certain substince in semen that couses the uterous to contract and (I believe the same substince causes) the cervix to open. This substince is given to women in hospital, however it is taken from pig semen! This substince is proven to work ten times better when taken orally. So, you can always try that.
I have not tried this, so I don't know first hand.
Ok, I may have some of these facts a little off (so someone could straiten me out,) but that's it for the most part. -Sorry if I grossed anyone out, this subject usually does.
