i have been taking my birth control for almost 8 months now and only slipped up about 2 times. I ended my period on Friday may 31, 2013 and started my other pack the following day (June 1st) and had unprotected sex that night. it was the first time for both of us and thought I would be fine considering im on the pill, but I didn't take the second pill in the pack till later in the day today(June 2nd). I don't really know how conception works when it's after your period and how pregnancy can be affected when on the pill. I'm only 17 and I'm just really scared about something happening, so as much information as you can provide would be so helpful!
