Pelvic pain?

Me

My little one is 15 weeks old, and almost every morning I wake up and my pelvis aches. It’s just a dull aching pain and it does eventually go away when I get up. Nothing seems to make it worse or better cause I’ve tried stretching and have been working out lately. Anyone else have this? How long till it went away? She was born vaginally and her head came into the birth canal slightly crooked and caused A LOT of hip pain during delivery. I’m thinking my pelvis just spread a little too wide or something during birth.
