I had sex yesterday and the condom broke and we didn't know. I took Plan B 26 hours after on top of taking birth control every day. I started my period earlier this morning and usually it is a lot worse than it is right now. Does Plan B make your period lighter this quickly?
Hi Guest,
Plan B can change your period, yes.
But, you didn't need it anyways. Having sex just before your period it is unlikely you'd get pregnant.
Hope it helps.
