Yet another pregnancy question

Okay. About a month ago I slept with a dude during my fertile window (if that’s what it’s called) we used a condom but I didn’t actually see the condom afterwards but he said he finished inside it.

My periods about week late but I’m experiencing cramps and spotting.

What r the chances that I could b pregnant?

(I am gonna do a test tomorrow I just need to ease my mind to some degree before)
