I had the stomach flu and than took pepto to soothe he stomach and now i can't poop and am cramping?

Eat: lots of fiber, drink plenty of water and if that fails can try stool softners or laxatives

May be fine soon: It is not unusual to have some change in bowel habits after a viral illness. It usually resolves in several days. It may help to drink plenty of water, eat a gentle diet, and consider eating more yogurt and other probiotic rich foods. Hope you feel better soon!

No BM: taking Pepto Bismo is sometimes used to treat diarrhea but may cause the opposite effect and cause you not to go to the bathroom. I would drink extra liquids and eat soft foods like oatmeal, soup and bread. If it does not get better in a day or two, you should see your doctor to get evaluated. Most stomach flu symptoms should go away in 2-3 days
