I am on regular birth control pills. I took Plan B the first day of my placebo week because of condom failure. Could Plan B make me miss my period?

I am on regular birth control pills. I took Plan B the first day of my placebo week because of condom failure. Could Plan B make me miss my period?

Maybe: If you were taking the birth control pills regularly it is very unlikely that you would become pregnant...Even with a broken condom.

Just begin your next pill cycle on the correct day. Get a pregnancy test done to prove you are not pregnant. ...Read more
