Irregular periods following introduction of hormonal birth control is very common. It reflects your body's efforts to recalibrate hormones with new levels. It can take up to 3 months to resume normal cycles. Additional side effects include nausea/vomiting, headache, painful menstruation, changes in weight. You may be one of the lucky few who end up not having periods on oral contraceptives.
