Hi. I started my new birth control on Sunday, January 28th. I take it at 7 am every morning, never missed. On Saturday, February 3rd, I had sex with my boyfriend. He wore a condom, but it broke. He didn't ejaculate inside of me. But there could've been pre-ejaculate inside the condom. We had sex around 9.30 - 10.00 at night, so about 10 hours until I took my first pill for the second week. How big is the risk of me getting pregnant? I'm planning on taking Plan B today, which will be almost 72 hours. Thank you for the help.
