7 weeks pregnant, had a bowel movement and wiped a lot of blood...

So I had a bowel movement about an hour ago and when I wiped I saw a lot of blood. I freaked out and staring wiping my vagina but it was dry. No blood. I have no cramps, no pain, nothing. I'm assuming the blood came from my butt. I also want to add that I've had blood when I wiped after a bowel movement quite a few times before I got pregnant. 
Have anything like this ever happened to you?
