?? Right side cramp ??

Kristin • Daughter was born June 30, 2015 🎀
I'm 17 weeks and I'm having a cramping pain on my right side under my rib. It's not sharp, it's like a dull ache. I feel better when I lay down on my left side or sit down and recline. I'm gonna call my doctor tomorrow but I'm guessing it could be baby making room and pushing my insides? Hope that's all but it's so uncomfortable 😞 anyone else have this?
