Late period HELP

So I had sex about a month and a half ago and the condom broke so I took plan b. I again had sex a couple of days later with a condom. I never got my period that month but I have had tender breasts, white discharge and it feels like I have my period. My next period is supposed to come tomorrow, could it be that I skipped a period because of the plan b? I'm really nervous and my stomach has been feeling weird, really not hoping for an accidental pregnancy haha HELP
