So I'm 17 and have been with my boyfriend for 3 years! I was into my boyfriends house for 12 days and we had sex multiple times during those 12 days with no protection and him ejaculating in me. I don't want hate because if I ever got pregnant we would be blessed and have a very supportive family! His parents went on vacation and he's working and just finished his last semester of university so I stayed in and cleaned and watched their dogs :) so I heard that birth control stays in your system once your on it for so long but I've only been on it for 2 months and if I took my birth control this month it would've been 3! I just want to say that I misplaced them and had no time to get another pack,my boyfriend lives 1hr away from me.
