I had a baby 10 weeks ago and I just woke up having bad contraction pain. I'm in the bathrm pushing and now and then I pass some gas. What could this b?

A GI issue. Clearly you are not worrying that you are in the throws of a very early miscarriage at this time. GI issues are almost always related to diet. Anyone else in the family who is eating the same food have the same symptoms? Check your diet for foods that cause gas and eliminate them.
