Taking emergency contraceptive pills once in a while is not harmful, but it may cause adverse reactions.
Emergency contraceptive pills contain a large amount of progesterone, so after taking them, they will interfere with the female reproductive endocrine axis, leading to hormone level disorders in the body, which will lead to the symptoms of vaginal bleeding, and the menstrual cycle will also change. In addition, the drug will also stimulate the gastrointestinal tract, and most patients will experience nausea and vomiting.
Although the side effects of emergency contraceptive pills are many, the drug is usually metabolized within a week, the body with the metabolism of the drug will gradually return to normal, and does not bring obvious harm.
It is best not to take emergency contraceptive pills more than three times a year, because it is easy to cause the body’s hormone levels in a short period of time to change, so it will also change the shape of the uterine lining, triggering irregular menstruation. In severe cases, amenorrhea and infertility can also occur.
Therefore, instead of using emergency contraceptive pills as the main form of contraception, it is recommended to use condoms or oral short-acting contraceptives for contraception.
