pain in my pelvic area!! normal??

so this is my third and final pregnancy I'm 31 and 4 today and even though I slightly had this same feeling with my second this time around it is absolutely horrible!!! I feel like my bones are being kicked or stabbed constantly!!! Nothing seems to help and sitting down makes it even worse to the point of tears! granted my second child is only 11 months old tbis month so I know my body has been through a lot the last year and half but IDK if I should go in OR is it just my bones moving and getting ready since I'm getting farther along. has anyone else had this?! I have an us on Monday so if it's somewhat normal I will wait until then to go in and be checked out but if not then I'll find a sitter and go in today!
