pain !

Hey ladies I'm currently 33 weeks pregnant and for the past week I've been having pelvic pain it's also in my thighs! Last night I can say was probably one of the worst nights so far. I was laying on the left side and I tried to turn and I got stuck the pain was horrible my husband had to help me roll to the other side and I heard a pop noise don't know if it was my bone or not but it didn't hurt lol. Literally all night I was screaming in pain while turning. it's now 9 am I'm finally up and it still hurts like hell! my husband is worried and thinks I should go to the er but I heard that this was normal? anyone been thru this ?!
