I had the stomach flu and i took pepto bismal to soothe my stomach and that was a day ago and i still haven't been able to poop what should i do?

It's alright: Drink plenty of water. Walk. If your stomach will tolerate it, eat some bran cereal or vegetables. You'll be fine soon enough. Sometimes, after a stomach virus, your bowels slow down a little for a few days. Don't worry.

Drink water...: eat a balanced high fiber diet and give it time. You took a medication that is used to stop diarrhea - sounds like it worked. Yes, pepto can lead to constipation; however, one day without a BM does not concern me unless you are very uncomfortable. Resume healthy habits and your bowel patterns should normalize - if they don't then see your doctor.
