Hi, Yes! Getting pregnant is related to ovulation — the time that a girl is most fertile and has the highest chance of getting pregnant. A girl with irregular periods still ovulates, just not on a regular, predictable schedule but since you are on Contraceptives ovulation gets delayed. People who take oral contraceptives, or birth control pills, generally don t ovulate. your ovulation will stop, and your period is not a “real” period, but rather withdrawal bleeding so you need to have a talk with your gynaecologist and take ovulation inducing medications if prescribed and plan for your pregnancy. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Minaz Kagadkoti, General & Family Physician
