A full cycle of the pills.
working in a pharmacy I recommend at least one cycle of pills taken at a regular intervals. Missed pills especially during the first pack can be a problem. Make sure they are taken at the same time everyday as to keep your hormone levels regular. Backup methods should be used if ingaging in itercourse within the first month or after a late or forgotten pill.
