I'm 33 weeks pregnant and have been having sharp pain in my pelvic area since beginning of 2nd trimester. My drs say its because of the the pelvis stretching to make room, but it's gotten worse in the last few days to the point where I'm struggling to get up after being seated, or laying down. I've tried tylenol, as suggested by my dr, but it doesn't work and can not sleep without a pillow between my legs to alleviate

the pain. I just want to know how much pain is normal and is it an early sign of labor?
