Eternal Question- when to start next packet of oral contraceptive pill
The first packet of OCP- pills is started right on first day of the menses.
One tablet every day after food , preferably on same time.
When packet is finished, give a gap of 7 days.
The day gap is over , next packet is started.
Irrespective of the day of menstrual cycle
The rest of all next packets are started with gap of 7 days.
