Am I pregnant?

My period is due in 7 days. Some of my boyfriend’s precum (barely any) got onto my clit about three weeks ago, I freaked out and wiped it off with toliet paper, but I didn’t wipe it into my vagina. I’m worried that somehow it got into my vagina and now I’m pregnant because I’ve been having cramps and some clear discharge with blood streaks in it. Please help I’m actually worried sick because I’m not ready for a baby and also the sex Ed at my high school was horrible
