right side pain. 14 weeks pregnant

I am currently 14 weeks pregnant with twins. I have felt great the entire pregnancy so far. I definitely have a baby bump. But for the past couple weeks after I get up in the morning and get to working around the house my entire right side of my stomach just aches! It is so uncomfortable, and makes it hard to even stand. I have had no other issues other then the side pain. I just assume it muscle stretching. But has anyone had this and have you done anything to get any relief!?
