I have a cramp like uncomfortable feeling all throughout my stomach n now i'm starting to feel nausea. i've been ttc w/no luck tho. wat could this be?

Cramps and nausea: There are lots of reasons for abdominal discomfort, and not all of them are due to the GI tract. Even "functional" syndromes may be present without underlying "disease." if pain with meals consider peptic (acid), biliary, or pancreatic disease. If bleeding or tenderness is present, this suggests inflammation, ischemia, or infection. Exquisite tenderness is quite concerning. Please see your doctor.
