So last week my birth control refills were over and I couldn't get an appointment until this week so I was basically out of birth control for a week. On that week I had unprotected sex the next day I took the plan b pill. This week I got my period 17 days earlier due to the plan b pill. I also had my doc app and got my refills today and had unprotected sex . To be safe should I take the plan b again or start my birth control and if I start my birth control will be effective ?
