I NEED IMMEDIATE ANSWERS PLS

Olivia
Earlier today I was cramping and yesterday as well. Now just a little while ago me and my fiancé had sex and then when I went to wipe there was just a little blood mixed in. And then there wasn't anymore. I just got off of my period 2-3 days ago. What does that mean? What could it be? Is it just from my cycle? That's never happened before.
