Hi, Frequent intake of contraceptive pills in high dose can affect your menstrual period and ovulation by altering the hormonal levels. So usually repeated intake of pills in high dose is not recommended. But as at present you are not having another alternative and as you are not sure of your ovulation because of previous intake of pills, you may go for pills this time. But the points are to be remembered: -Better to take any medicine after consulting your Gynecologist. If you are having any history of hypertension, diabetes, obesity, smoking habit etc, taking high dose pills is not advisable. -As you are taking the pills for the second time it may disturb your regular menstrual cycles and you may not get periods as expected. -The contraceptive efficacy of the pills depends on how early you take the pills after intercourse. -From next month onwards better to go for some regular contraceptive method like hormonal pills, progesterone injection, etc with your doctor s advice, to prevent major disturbances in menstrual cycles which can affect the future fertility. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Sree Gouri SR
