Spotting?

Jillian
Okay so TMI but every time I wipe today there's a little bit of blood. It's not enough to leave a mark on my underwear but more than if there was some sort of tiny cut or something. 
I haven't had sex since April 23 (my husband is in the Air Force) and I had a full period last week. It just ended on the 23rd. Does anyone know what this could be?
