Hi I'm 21my name is charday I purchase a plan b pill July 22/13 this month on a Monday afternoon and took it. I had sex again like around 2:30am and again around 4:00am unprotected again like 2 days ago does the pill that I already took still takes affect or should I repeat another dose of the plan b pill before the 3rd day and is it safe to take again?? help what to do I don't want kids yet
