You should not take the emergency contraceptive pill more than three times a year and not more than twice a month. If you take the emergency contraceptive pill twice in two months, the effect is not very big, but if you take it again, it may cause endocrine disorders and irregular menstruation. Because this drug is a highly effective progestin, it can disrupt normal ovulation and change the environment in the uterine cavity, so it can cause endocrine disorders in women, resulting in non-ovulation and playing a contraceptive role, so this drug cannot be used as a regular contraceptive measure. If you don’t have the requirement to have children and have a normal sex life, you must take effective contraceptive measures, and taking emergency contraceptive pills for a long time is not possible.
