I had sex Tuesday night going into Wednesday it was 12:30am-1:00am and Thursday around 12-1pm I went and got the plan b because I had sex but the man said he didn't ejacualete in me, but I did it just to be cautious I had brown discharge 1-2 days after taking plan b and it's been 7 days sense taking plan b and I still haven't had my period I've had lower back pains and a few light cramps in my hips but that's all, I'm scared that I could be pregnant I also took the nexaplon out of my arm a month and a half ago
