Hip problems ?

Not sure if this belongs here. My little dude is 13 months. Since I gave birth, my hips have been cracking and popping a lot. It’s gotten progressively worse and worse. I can be sitting down and if I lean forward it locks. I have to keep leaning forward until it “pops” and it feels better after. I will call my dr tomorrow just to see what he says but anyone else experiencing or experienced this PP?
