do i take this as not pregnant?

hey y’all. i posted a day or 2 ago about taking the generic plan b and also on birth control. my period was supported to come yesterday but i think it came today. i know that spotting is a symptom of plan b, but there is a lot more than just a few spots of blood. did my period start or is it just post plan b bleeding? for context i am on the mini pill, my bf pulled out, it was the first time for both of us, and i took a my choice the morning after (one choice? the generic plan b). it happened on wednesday (day 22 of my 28 day cycle) and i took plan b thursday morning (so a week ago) can i safely assume that i am not pregnant? i have been having so much anxiety about this and we have decided to wait till we’re married to do it again. my period symptoms have been weird, normally i get really sad right before, which happened, but i also get bad cramps and a slight nausea the first day. i had this on monday/tuesday (i didn’t take my BC until late monday night and i thought that might be why) but yeah i’m still slightly worried but also i second guess absolutely everything
