My period was supposed to come three days ago but I took plan b on Sunday because condom broke and even tho I was gonna get my period I just wanted to be extra safe. My last time having sex since Sunday was February 20-21 and I’m a 100% that I practiced safe sex. I guess I’m wondering if the reason why my period is late is because I took plan b also I am kinda stressed out because of my period and as well of this whole corona virus thing. Also I heard that taking plan b 2 days before getting ur period is kinda of a waste but on the packaging it said nothing about taking it a precise time of menstrual cucle
