Tears or period?

Lily

So I want to say I had unprotected sex on April 3rd but took the plan b pill right away. And yesterday my boyfriend finger me but the next day I start feeling pain as if I have a tear but I also felt cramps and I was bleeding. I don’t know if it spotting because it didn’t seem little but idk if it a tear blood. My period in app said was supposedly come at the 23. Any idea what it can be?
