🆘 Help a worried girl out please 😭

So my bf and I always use condoms but 3 days ago we were drunky and broke 3 condoms, the next day we got plan b (as I am not on any other form of BC) I took it and was suppose to start my period yesterday (eve has always been accurate for my cycle starting) and I’m kinda freaking out that either the plan b didn’t work or is it just bc I took a plan b that my period is just a few days delayed??? Should I be worried????? SOS
