Emergency contraceptive pills are hormonal medications and should not be taken more than three times in a year or more than twice a month. If this range is exceeded, it can cause changes in endocrine hormones in the body, which may lead to endocrine hormone disorders, polycystic ovary syndrome and even increased prolactin. Emergency contraceptives also cause prolonged disruption of the menstrual cycle, and when the menstrual cycle is disrupted, ovulation may also be disrupted, which is not conducive to conception and may affect the chances of pregnancy. Because each person’s constitution is different, some people may or may not experience this, so it is recommended to observe. When endocrine hormones cause menstrual disorders, it is best to go to the hospital for endocrine hormone tests to determine if there are any abnormalities, and depending on the situation, symptomatic treatment can be carried out. It is recommended that during the period when you are not preparing to have a child, you try to take condoms or intrauterine devices to avoid the increase in the number of oral emergency contraceptives, which can cause damage to your body.
