Bleeding after BM

Courtnie
Sooo I'm constipated, what a shocker, and lastnight strained a bit in the bathroom. When I wiped there was a very very small amount of bright red blood. Wiped a few more times, nothing after that....of course I'll continue to monitor it but is that normal?? I'm positive it was from the vagina, after I saw it the first wipe I "focused" on that area only to see. Help! I'm nervous.
