You : You are definitely at risk for pregnancy, though it's hard to say if that is what is causing your stomach pain. If your pain continues, you should go see a doctor. If you are concerned about pregnancy, you can either take a home pregnancy test as long as it has been 5- 6 weeks since your last normal period, or you can go see your doctor and they can test you. A home pregnancy test is 97% accurate if taken a week or more after the missed period and a doctor's test can tell around when you should be getting your next period. Good luck!
