Colon cancer?

Hey ladies, so first off please be nice, I have major anxiety.. I’ve always had stomach issues.. about three weeks ago I had diarrhea a couple a times for two days, with cramps and just not feeling well.. then that next week, I get a Hemorrhoid I was down for three days, I’ve never experienced one before. Then my upper stomach starts hurting and I have gas pains but it feels like I can’t pass gas, (maybe from an internal Hemorrhoid?) all that week my stomach hurts low and lower pain plus plus my period comes so that doesn’t help.. I know some of you will say go to the doctor, but before you say that I have an apt scheduled. I just wanted to hear your symptoms of colon cancer.. I’m 29 I know colon cancer is on the rise for young people please help ease my mind or give it to me straight.
