I recently started taking birth control pills again (Yasmin 21 pack) after being off another for a little over a year. I started my second pack on saturday but had sex six days later and my partner ejaculated in me. We normally do use condoms. Now we are both worried whether or not I could become pregnant. I take my pills regularly. I was also taking Ponstan with my first pack for 2 days recommended by my doctor, and though I was told it would hav no effect on the pill I am still a bit skeptical. Am I really at risk of becoming pregnant having unprotected sex so soon after starting the pill? Should I consider taking the Emergency Pill as a precaution?
