I started talking the pill when I was 15 in high school to help acne- was not sexually active at all until I was 18, then switched to the implant for about a year and didn't like it- I haven't been on any type of chemical contraception since (still with the same bf as I was when 18) but have recently taken up the pill again for my acne- how long do you have to be on the pill before you can have sex without a condom?
