It's almost 3am and here I am lying in bed with excruciating lower left pain localized in the front of my body near my hip. It started last night before bed and hasn't changed no matter what position I am in. I've noticed it gets worse if she moves or if I move.  I'm almost 31 weeks now and my initial thought is that is where her shoulders/back were about 4 days ago re: ultrasound. The pain is more of a sharp stabbing pain in that area. Should I be worried? I reallllly don't want to pay to go to the ER as the doctors office is closed tomorrow due to Memorial Day. Has anyone experienced this?
