Should I be worried?

My boyfriend and I had sex on Tuesday and he was going really fast and hard and I was ssuuppeerr wet and his dick slipped out and hit my bootyhole. It literally hurt so bad that i thought I was going to pass out and my butt was sore the day after. 
I just pooped for the first time since then and when I wiped I noticed that there was a lot of blood. I didn't feel any pain while I was pooping but? 
Anyway is that normal? Should I be worried?
