Protected =likely: If you have followed your BC pill instructions & never skipped any of your daily pills, you are likely protected.Pill failure rate is cited at about 5%/yr. People can get pregnant (not common but possible)on their period & plan B works better when taken sooner after exposure, but given all you did you are likely fine.
