I recently started Levora on Monday. This is the first time I've taken any form of oral birth control. I've been on it for four days. I took it on the first day of my period. The instructions in the pamphlet say that since I started on the day of my period, I won't have to use any back-up contraceptive. I had unprotected sex after the fourth day. Am I in a high risk for becoming pregnant? I've read online and it says that I should have waited at least seven days before I had unprotected sex. Other sites say after my first full cycle. But the pamphlet says that I should be fine since I started on the first day of my period, and my period has already stopped earlier than usual. Do you think I'm safe? Help Please!
