I'll make a long story short. Me and my boyfriend have done a bit of genital rubbing without protection at one point, and i took plan B asap (13 hours after). I got my period a week after that, and it was very heavy and lasted about four days. Me and him have done the whole genital rubbing thing ever since, but with the use of a condom (he never ejaculates while im on him), and we are extremely careful with it.
I have not gotten my period for about 7 weeks, but I am also very irregular. I took two at home pregnancy tests and both tested not pregnant. Is there a possible chance of me getting pregnant this way? Or should I just wait for my period to come and not worry?
