So this might get confusing but i was on Yaz for about a year. Then my doctor retired. So until we could get an appointment for a new birth control I got a month pack of Yazmen but there was about a 2 week break until I actually started yazmen. I took that until my new doctor put me on Lo Loestrin. The same day I took my first pill of Loestrin, my boyfriend and I had sex and the condom broke. The next day I took the plan b because we were both freaking out. I just kept taking the pills as normal. My boy friend thought plan b and bc canceled each other out but I have no clue. And I wanted to know the side effects of doing what I did. And if there's any chance of pregnancy because of all the switching pill brands.
