Could I be pregnant?

Me and one of my best guy friends slept in the same bed at a party and ended up making out and I gave him head and we didn’t have sex but I was on top and we didn’t have pants on. He couldn’t get fully hard bc he had whisky dick but we still were trying and he claims he didn’t cum. But my period is 4 days late and I’m not sure why because it is never ever late. Could I be pregnant or what ugh

So my period still has not came. It’s been 6 days and I have no signs of my period other than my boobs being sore. Sometimes when I wipe I get like a weird brown color goop in my underwear and I am constantly all the time wet all the time. I just don’t know what to do
