Could i be pregnant?

Patient: I was suppose to start my period 16 Nov but i started taking my birth control 13 Nov (sunday) well i missed days and tried to double up until i just gave up because i was forgetting to much and stop taking them 23 Nov. My husband came home 16 nov so i wasn’t even on the pills long enough to take effect. Even though i had a cycle when i stopped taking the pills is it a chance that i could be pregnant or no because my period was already scheduled?
