Prego or not ?

So on saturday morning (31/10) m partners condom broke,, literally two hours later i was at the gyno (where i live dont sell mornig after pills) she prescribed 4 gynera pills for two days, which i took on time,, im not on BC and so i really dont want to get pregnant.
My period was on 11/10 (cylce length 37!) anyone have any experience with such situations? Cz idk how to calm down.....
