anyone else ???

Anyone else (that's pregnant) have an issue with their pelvic bone popping out of place on one side ?? Mines do this everyday and my doctor hasn't checked it yet but in the morning I'm going to nag him about it as soon as he walks in . It's hurts so bad and at times I can hardly walk. 😪 it's so frustrating because I'm big as a whale and then this pain on top of the baby weight is tiring. Anyone know what it could be ?
