I was wondering what my chances of pregnancy are? My boyfriend and I were having sex and the condom broke, but neither of knew it until after he ejaculated inside of me. I am on birth control, but I only just started it about two weeks ago. At the time of the sex I had taken twelve pills and right after sex I took my thirteenth because it was the time of day I usually do. I have been taking my pill (ortho tri cyclen lo) regularly since then. I wasn t sure if the birth control had kicked in yet or not and I wasn t sure if it had stopped ovulation yet (because it did happen during the time of the month I d be most fertile if I was ovulating) so I went to walgreens and picked up plan b one step and took it with in and hour and half of having sex. I realize that birth control and plan b one step is a lot of hormones, but I just wondering what the likelihood that I am pregnant is? Thank you!
