Hi there! I do not know if you realize this or not but you did post this in the mens forum, not that it matters but yes you can get pregnant on b/c pills nothing is 100% except abstinence, if you feel you are pg you should talk to your Dr. As I am no Dr. And if you are preggars discontinue using your b/c pills as far as the sex thing, that is your choice. Have you taken a home pregnancy test. If you are missing your period that could be because of stress too.
Good luck to you!
Let us know what you find out!
Good luck in nursing school!
