Why am I so gassy from the back end? I don't think pregnant is ruled out haven't had unprotected sex for 3 months and had 5 neg test bled each month?

Flatulence. Flatulence is a symptom of a healthy high fiber diet. It can also be a sign of a food allergy or intolerance. It in no way is a sign or symptom of pregnancy, so have no idea why you are doing unnecessary pregnancy tests when you have periods (periods are the physical proof that one is not pregnant). Many people with unexplained flatulence are taking too much caffeine.
