There is no withdrawal bleeding, which does not mean contraceptive failure. If you take the contraceptive pill for more than seven days, the endometrium itself is thin, and even if the contraception is successful, withdrawal bleeding does not necessarily occur. Normally, withdrawal bleeding occurs about a week after taking the pill, which means contraceptive success. There is no retreating bleeding, and menstruation needs to be observed. If menstruation comes normally or is delayed for less than one week, it means that pregnancy is ruled out. If menstruation is delayed for more than one week, the possibility of contraceptive failure cannot be ruled out. It may also be caused by the side effects of contraceptives, and it needs to be determined by blood sampling to test human chorionic gonadotropin. Contraceptives affect the endocrine system. It is better not to take them more than three times within a year.
