I had sex the night before I was suppose to have had my period.When I woke up early that morining I was really scared cause I am not completely sure about how safe I was that night. So I took excatly 12 birth control pills (lo oveal) that day which is the (day I was suppose to have my period). And also (it was birth control I have not ever took and I used my friends. And I haven't been on birth control in 2 months). Now my period is 4 days late I'm wondering could it be late because I took so many birth control pills that day? and when should my period come?
