I took a plan b the last day of my period, that was 4 weeks ago and I still haven’t started my period I’m 7 days late. I’ve taken 3 pregnancy that have same back negative. But 5 days ago I had sex again and I was giving head naked and sum got on the clit when he came but I whipped it off immediately and washed it off with water, then 10 minutes later peed and showered but everyone said it would be impossible to get pregnant from that. But my boobs have been sore ever since the day I was supposed to start my period and I was really moody the whole time it was supposed to start. Ik I did read the Pamphlet about the side affects but it’s been 4 weeks and I’ve read that it’s supposed to start by now. I’ve also been really stressed about all of this so that could be a reason it’s so late too. But what should I do, should I be worrying?
