undiagnosed stomach problems help

[constantsorrow]

I do not know what is wrong with my stomach. I have been having problems ever since eradicating H pylori. my doctor has prescribed me prilosec, pecid tablets and other acid reducers which helped at the time. But now my symptoms seem to be getting worse. At a recent appointment when the doc pressed down into my stomach above belly button or near it I felt I had to have a bowel movement, the sensation afterwards was unpleasant and stayed with me for hours.



Symptoms - pelvic pain- (Began the third day of my cycle and lasted 2 days)
                  blood in stool/ (or at least in the toilet bowl and paper, stool was not black, but is sometimes dark                though not always.
                  gas
                  bloated -( Its hard to describe how my stomach feels but it is a very uncomfortable sensation)
                 stomach- makes noises even when I don't eat anything
                 constipation- ( I try to eat foods high in fiber but even when I do there is never enough stool.
                 stomach feels odd- after having a bowel movement

Yesterday I had abdominal pain while eating and had a bowel movement that was loose. There wasn't much of it.

Does constipation cause all these or are they symptoms of something best understood by colonoscopy or endoscope? what could it be?
