Sharp pains in my pelvis 39+5 possible sign of labor?

Lisa
Ok ladies, I've been having these intense sharp pains in my pelvic area for the last 45 minutes or so.. They make me want to curl up in a ball or walk hunched over if standing up. I was 50% effaced at my appointment yesterday and 1/2cm dilated. I also ate half of a pineapple today. I've he Braxton hicks but nothing like this yet! They friggin hurt!!!!!!
