emergency contraception
"My period usually comes on towards the end of the month. N my boyfriend and I had unprotected sex on the 2nd and I took the pill that same day. The 8th of that month my period came on ( it came early ) n by the 15th it was still on and I was a lil worried because its been 8days that my period has been on. The 16th came and it went off but the 18th came and I started bleeding again. It's like I'm having a 2nd period "
