I had sex on Saturday May 5th at 3 am. Then that same Saturday night I drank.. but not too much. I never threw up. But that Sunday morning at about 10ish I took only one plan be pill. Am I going to be OK? Hh

You'll have to wait and see what happens when your next period is due. Plan b is effective, but no form of birth control, including emergency birth control is 100% effective.

Ok thanks

No form of birth control is 100 percent, the longer you go from the time you had sex, the less effective Plan B is. So you will not know till it is time for your next period and see if you get it.

But also plan B often makes or effects your parents
