Plan B?

Odd question. Just started a new birth control on the 9th and went to see my boyfriend on the 10th. We didn't do anything our first night, but when we did it we couldn't use condoms because it hurt me. So.. Instead we just did it and after two days and several times, I took the plan b pill. I know, totally stupid. Worse than that is for three days we did the same thing. Went at it as much as we can handle then on day three took the plan b pill.... I did research on it and I know you arent supposed to take it like that but I did. And I was just curious if its still possible to end up pregnant. Everything I read said it was highly unlikely but we did a lot in three days and basically waited till last minute to even get the pill.
