Sharp pain in stomach?

I'm 15 weeks 3 days today. Last night I was laying in bed when all of a sudden I had a sharp pain an inch or so to the left of my belly button. It was so bad that I was rolling around on the bed crying for 20 minutes. It went away and I went bed. As I woke up throughout the night as I always do, I'd feel the pain lightly as I moved but it would go away and I'd go back to sleep. I woke up this morning and got up to go pee and brush my teeth and I couldn't even stand up straight. I called my midwife, and I'm waiting for a call back. Has anybody else had this?
