38weeks what is this pain?

Crystal

Woke up feeling like someone hit me with a baseball bat on my vagina/ pubic bone. When I walk it hurts, getting up, sitting down it hurts. Anyone else feels this way?

p.s. Had an OB appointment yesterday, he said I'm 1.5cm dilated, 50% effaced & could feel top of baby's head. Also said it could be anyday now.
