I had sex on Monday about a week before my period and the condom ripped although he pulled out he still finished outside on my vagina i took Plan B just to make sure but how do i know it worked? I took it about 2 hours after it happened and a few days later I started getting cramps like i was about to get my period. I finally thought I got my period today 5 days after taking the pill but after a couple hours all I had was brown discharge. Someone help me and let me know why this is happening? Could I possibly be pregnant?
