Hi, Thanks for posting in HCM. I understand your concern. Femilon contains Desogestrel & Ethinyl Estradiol. It is a combined oral contraceptive (birth-control pills) are used to prevent pregnancy. Combination hormone pills like Femilon tablet can be used to regulate abnormal menstrual cycles. It does not affect for becoming pregnant in future. Moreover, the chances of getting pregnant would be higher when your menstrual periods are back to normal as ovulation would happen at right time during the regular menstrual cycle. Hope the information provided would be helpful. All the best.
