So this is my 3rd pregnancy. I am 37 weeks.. Every time my baby moves it hurts something inside. Or I can feel her head in my pelvic bone (if that's what it is) sorta like a sharp pain in my vagina. Its almost like if she doesn't fit anymore. With my other pregnancies it was never this painful.. Could it be she's to big ? I've had small babies and my stomach has always been small during pregnancies..
