... protected contraception-wise if I've been taking it for 18 days? I know you're meant to start on the first day of your period but I didn't get the prescription until the last day. I'm taking it both for contraception and acne prevention and didn't want to wait a month to get rid of my acne. I had sex last night, with a condom. The condoms didn't break or anything but we did it 3 times in a row, so I'm worried that somehow some sperm may have gone rogue (sorry TMI!). Basically, I'm asking is the Levlen already working as contraception or was I relying completely on condoms? Any help would be much appreciated!
