I Think For The Past Month And A Half My

I think for the past month and a half my stool would bleed dark blood when I would have a bowel movement, every few days and then go away. No pain just a itchy afterwards and my poop wouldn't be solid. I didn't have the colonoscopy done last week because it was too expensive with my insurance, I think I might have to pay the 275 now to find out what's up with me, I'll be 42 in a few days.
