Birth Control taken late before period and then had sex

Ok so i’m really freaking out because i have a birth control reminder app that tells me when to take the pill but one day last week i totally forgot about it and took it at 7 in the morning when i usually take it at 9pm

the app says that i am not protected from pregnancy because i didn’t take 7 consecutive pills( on time)prior to my period

but i had sex yesterday after having taken 6 pills this week so far. I’m on low-ogestrol 28.

could i have gotten pregnant?

please help!!!!
