Possibly pregnant??

I took plan b July 14 which was the day i ovulated and then got my July period (just a week early) and in August as well. Last Friday i had unprotected sex and took plan b the next day (less than 24hrs). Now eve said i was ovulating and he didn’t cum but I’m worried about Precum. It’s been 3 days and I’m moody irritated and my lower stomach feels crampy and since last night up until now i have this fullness feeling in my lower stomach and it feels like i need to pee. I have no other symptoms am i pregnant? (My period cycle ranges from 29-33 days and according to eve my next period is in two weeks...could i be pregnant?

Ps: i broke up with my ex last Friday so there’s no need for me to go on birth control anymore cuz we ain’t together
