Did anyone’s pelvic bones shift after giving birth?

I have a hard bump/bone sticking up on the left side of my pelvic bone. It doesn’t hurt or anything, you can’t see it, only feel it. but it almost feels like the bone is sticking out..did this happen to anyone else? Hoping that’s what it is, is just my bones being out of place, not something worse. Just hoping for some insight to hopefully make me feel a little more at ease before going to the doctor
