Jess, I used The Pill, too (different brand), and I didn't get pregnant. There is always a risk, and some women get pregnant, even if they take The Pill correctly, but the odds are in your favor for not getting pregnant. I personally recommend using condoms in addition, although I didn't with my current boyfriend (when we were having sex). But the condom will offer you some extra security. If you don't want to use condoms (certainly advised if you're not with one partner), you might consider a vaginal foam or something as a secondary protection.

Juliana, that's the same stuff I've read. You do good research!
