For the past 3 and a half weeks i have had an increase in gas. I feel bloated after eating. Im not sure if i'm constipated because i force stools out. Usually when i force out anything (usually a couple times a day) its easy to pass but small in amount. I'm not sure if im letting enough build up in me. I also have had an increase in mucus. It seems like every time i pass gas its wet (sorry i know its gross). And in the last couple days Ive had a very mild dull ache in my lower right abdomen near my hip. The pain is very brief lasting only a second or two but intermittent coming usually once or twice a day. The pain is worsened if i try to strain. My doctor thinks it has something to do with my gull bladder. I did have a pain under my right rib cage but has been very intermittent coming and going every other week or so. And i did see some undigested food in my stool one time through all this. I'd like to believe my doctor but im so scared its something really bad like cancer. No one in my family has ever had cancer and neither of my parents have colon polyps. PLEASE HELP.

P.s i did see blood on the outside of my stool a couple times in very very small amounts (Maybe a drop). However when this happened it was always after passing a hard stool. It may have even been food.
