condoms broke

my bf and i were having sex and he pulled all the way out and the condom broke when he went to go back in then a few days later the same thing happened (the condoms were too small and we kept them in our vehicles; we have bigger condoms and no longer keep them in our vehicles)

and then i started BC a few days later

i know there's always a chance of pregnancy but if there wasn't any precum (that we know of) i should be okay right? i feel so fucking stupid. i'm terrified

the first of 'this month and 28th of july are when they broke i'm supposed to start my 'period' in 3 days according to eve. i started sugar pills sunday(august 20th) and am kinda cramping right now but i can't tell if they're period or poop related.

i also assume if i dont bleed then to test.
