Plan B & period

Wednesday the 19th was my first time having raw sex. I took a plan b the very next day (8/20) then the next day 8/21 my boyfriend and I had intercourse twice both times with condoms my tracker said I was nine days from at the time and approximately 22 days from my next ovulation. Reading the tracker now I’m three days away from getting my period however I’m not cramping per usual only having slight discharge that’s yellowish I googled and it says may be pregnancy .. can somebody help me out
