Stomach pains...new symptom?

Carsey • Mommy 4.14.17
So 12 weeks hit and I barely have any nausea now (yay!) but now I get these stomach pains all of the time. It's my stomach not my uterus so I'm not worrying about the baby but it's really uncomfortable and keeps me up at night if it happens late. I can't figure out what causes it. Anybody else?
