IM SCARED. HELP!

Soo I’m like freaking out because I don’t know if I’m pregnant. I’m not on birth control and I haven’t had sex before but like 2 weeks ago I gave my boyfriend a blowjob and some of the cum was on his hip, I was sitting on him and we both still had our undies on. And I’m sure we wiped it off and whatever. My period is 17 days late and I’ve had pms symptoms. What’s the longest you’ve waited for your period? Is there a chance I could be pregnant? I’m sure he didn’t have cum on his fingers or hand when he fingered me.

UPDATE: I FINALLY GOT MY PERIOD LIKE A FEW SECONDS AGO I WAS ACTUALLY STRESSING SO MUCH THAT I WAS LITERALLY GETTIG READY TO DO A TEST AND THEN I TAKE OFF MY UNDERWEAR AND I SEE BLOOD AND I INSTANTLY FEEL LIKE IM FLOATING IN THE AIR BECAUSE IM THAT HAPPY!! AHHH. Lol I know my description sounded stupid asf but I wrote it in a hurry not wording it like it should’ve been worded😂. Anyway, I’m the happiesf person right know. I’m cramping but I’m loving it!!
