I just started a new pack of birth control pills

Patient: I just started a new pack of birth control pills (I’ve been on the pill for six months now) and with the new pack I decided to change the time to something more convenient but I am wondering if, because I changed the time, if I need to wait a week for the pill to become effective again or if because I’ve been in the pill for so long that it doesn’t matter?Thanks!

Doctor:
