There are short-acting oral contraceptive pills and emergency contraceptive pills that women take. The short-acting oral contraceptive pill is very effective in treating irregular menstruation in women, as well as endocrine disorders. In the case of the emergency contraceptive pill, this pill is a highly effective progestin that can cause endocrine disorders in women and can cause irregular vaginal bleeding. This drug has an effect on the body, so it can’t be taken more than 3 times a year, and not more than 2 times a month. Since this drug, if taken too often, can cause abnormal development of female reproductive cells, it may inhibit ovulation and cause abnormal follicle development. Therefore, this drug cannot be applied as a regular contraceptive.
