Last month while on my period the condom broke and he didn't ejaculate but I took plan b anyways, and then a few days later while still on my period it happened again except this time he did, so I took plan b for a second time. I was supposed to get my period on the 7th and it is now the 16th, do you think that is due to plan b and should I be worried that I have not gotten my period? We have had sex since then, but each time it was with a condom and none of them have broken.
