lower pain 37 weeks. advise please!!

anna

I am 37 weeks pregnant and my lower stomach right above my vagina (hate that word) literally all the way across is sore. when i stand up it hurts, when I walk it's sore. when I may down it's the worse it's like I'm internally bruised... I don't know if I should sum it up to the baby head getting deeper down, or if it's something i should go to the doc for. any advise ?
