Rib pain on left side!!!!šŸ˜©šŸ˜©šŸ˜©

I have the worst rib pain on my left side. I am 26 weeks and 2 days it started about three days ago. It hurts really bad when I cough!!! I'm just getting over a cold and have been doing a lot of coughing, don't know if that has anything to do with it. I think I over did it yesterday, I cleaned house and gave my dog a bath, and today I can hardly move!!! I've been putting a heating pad on it off and on. Anybody else having this problem? Or know what else I could do to get some relief?
