I have a strange hip, how can I fix it?

I am 14, so maybe it will fix itself in time but the problem is that my hips jut out like normal hips, but then were my pelvis is, at the side it goes in slightly then it goes out again where my thigh starts. It's weird and it makes me feel self consious when I were certain clothes as it becomes really obvious. If I run my hand from the start of my hip past my thigh, there are two bumps and it dips in between them. I'm average weight, 8 stone exactly and average height so I don't think it's because I'm fat...or maybe that's were my fat is stored but I really don't know an would really like to know how to get it go away.
