birth control is off a little everyday

hi so i’m on a combination pill and it’s my 5th month on it but this month i changed the time to later at night because of a new job. i’ve heard it’s fine to be in like a 2-3 hour window for your pill time but the first few days i’ve been a little off from 9pm. like 5,10,20 mins and now like 45 today. is this bad since it’s my first week again on the pill and the time is different now? i know i should set an alarm, i’ll be doing that now.
