I am probably the only one who didn't realise this. When you are due your period you get period pain, this is because the cervix has to open and dilate slightly to let the blood out of your womb This is why they say you get period pain in early labour as your cervix begins to dilate!! I didn't realise that, god knows where i thought your period came from then!! Lol. Just a bit of useless information for you.
