The emergency contraceptive pill can be taken at most twice in a year, and if taken twice in a month, the side effects are too great. Because the emergency contraceptive pill is a highly effective progestin, its progestin content is more than five times that of other contraceptives, so it will also cause some harm to the human body. If you take emergency contraceptive pills frequently, it can cause damage to liver and kidney functions, and can lead to serious endocrine disorders, which can cause menstrual disorders, or can lead to irregular vaginal bleeding. So it is recommended not to use the emergency contraceptive pill as a regular contraceptive method. It is recommended that it is best to use condoms for contraception if you are not planning to get pregnant, which is safe and simple, and has very few side effects and is clinically effective in contraception. If you don’t want to get pregnant for a long time, you can get an intrauterine device to prevent pregnancy.
