If you start on day 1 of cycle (ie the first day of period) and take 1 tablet each day at the same time each day (within 3 hours) Errin will be effective immediately (no other contraception required)
If you are more than 3 hours late or forget a pill take the pill as soon as you remember and continue as normal but use another method of contraception for 2 days.
