I don't know if I'm pregnant, HELP ASAP!

On Jan. 9 I had sex without condom for about 1 min or less, he didn't come inside, he did outside and after that minute that was it (yeah, it was short). So I didn't feel good about not using condoms but I accepted because my period is suppose to come aprox. in about Jan. 11 or Jan. 19 if late. And I've read on the internet if you have sex 12 or 10 days before your period you CAN'T get pregnant so I was about 2 day away (maybe because I don't know when I'll get mine) so I didn't worry and also, I bought the "day after pill" and used it 19 hours after the small action. Do you girls think I'll get pregnant? 😣 because I'm worried.
