Since you had taken the emergency pill twice during the same cycle, your normal hormonal
milieu is obviously disturbed. This would cause disturbed cycles. Please remember that safe period is from day 1 - day 10 and day 18- day 30 approximately in a 28-30 day cycle. Also, please use a regular form of contraception
and restrict the use of emergency pill to only a couple of times a year. Please consult your doctor for further assistance. Wish you good health.
