What Causes Abdominal Pain Along With Belching And Bloating?

Yes I have stomache pain pain under breastbone pain in middle of back and in the bend of my upper thighs. I guess that would be lower groin. I have gas belching and bloating. They say my gallbladder and ovaries are good. Bloodwork was normal. Stools are a dark brown instead of my normal light brown but no black or tarry stools. No sharp pains just dull ache and aggravating. Especially after I eat.
