Hello. So on July & August, my period arrived on the 2nd. But for September, my period did not come on the 2nd (i know it doesn t always come the same day). But I had unprotective sex on the 4th. It was only a couple minutes & he pulled out & ejaculated on my stomach. I didn t want to rely on pulling out. So I took plan B about 36 hours after. 6 days later, I am bleeding. So I am not pregnant, correct? & also i heard about a week after, u bleed from taking plan b. so am I bleeding because of my period and the plan b?
