Well it all depends since you did use protection and the condom was not broken and you also took plan B you should be fine!!! But i also have three friends that has unprotected and protected sex and took plan B and still "GOT" pregnant!! Best bet is to get on Birth Control and take it as directed and always wear condoms!! Plan B is ONLY for emergency use like if you have unprotected sex or the condom was broken or you missed a dose of your birth control but you still have a chance of plan b not working!! I myself have had a condom break then went in took plan B as prescribed and i was fine i did not get pregnant! Hope this helps...Good Luck and maybe you should try the IUD?!
