Hi, this is very embarrassing but I need some advice. I am 44 and am going in for a colonoscopy in two weeks. I have had this planned for awhile so I really don't want to cancel. Anyway, low and behold I will be on my period and for the first 3 days it is usually very heavy. It's very embarrassing and as I said, I don't want to have to reschedule. Am I in trouble?
