Pain in right side.

Hey ladies. I'm 37 weeks and have this sharp pain in my right side sometimes. It's not a cramp and I don't think it's a contraction. It's like and ache. It comes and goes but mostly when I'm laying down. I think it may be just sore from her pushing? Anyone know. I've been debating whether to call my doctor but no matter what I call for I always have to go in. If it's serious I have no problem being seen but when my doctor is an hour away going in just to be told it's normal or gas or something silly isn't really on top of my list of things to do today. Anyone have any ideas?
