I Had The Flu Back On The 3rd Of November.

I had the flu back on the 3rd of November. Dont really anymore cold symptoms but I have had some others. I have felt so nauseous for about a week. My stomach has been upset and I have had cramping on and off on my middle to leftside. It sometimes feels so tender to touch, and there are times when you can press down and when you let go is the worst pain. It isn't that bad unless you press on it. There has been a red blood in my feces and the paper at times. I have been having pain in my bladder on and off. Ive had trouble of having to go to the bathroom in a hurry if I get the urge to pee. Today I have peed on myself twice and had no control to get it to stop. I have a Drs apt at the local city clinic on Friday at 1.40. It was all thru had available, and I called on Monday. I'm not sure if I should just go in to the ER...
