Having some pain...what do you guys think?

Ak
Since Friday I have been having some pain in my abdomen. This is my first pregnancy and first child so I have nothing to compare this to. 
It goes from about my pubic bone up towards my right hip. It does not feel like cramps or what I think contractions will feel like. It is also not a constant pain and feels most similar to an overworked muscle. So some movements hurt or are uncomforable. I've heard of round ligament pains and I thought that I had that before but that felt more like stretching. 
Any thoughts on what this could be? Should I call my doctor? I am not having any other alarming symptoms. Just freaking myself out at this point really
