I Had A Colonoscopy On Friday The 8th Of April.

I had a colonoscopy on Friday the 8th of April. They found a couple small hemorrhoids and a very small pulp that the air blew out. The day I came home I felt great. That night I had bad stomach pain (upper and lower stomach). The next day passed blood in my stool. Now the pain is slit comes and goes. Stomach feels strained. There has been no more blood. I feel a little blotting. My Question to you is are these systems normal after 4 days?
