If the first month of the IUD, the menstrual flow is particularly heavy, it is recommended that oral tranexamic acid can be taken for treatment, which will achieve the desired purpose of stopping bleeding. Clinically, the IUD is a foreign body to the uterine lining, so there is a process of adaptation. Therefore, within three months, it may cause changes in the amount of menstruation or changes in the menstrual cycle, and it is recommended that clinical treatment be given according to the specific situation. The vast majority of people will adapt to the IUD after three months, and their menstrual flow, color, and menstrual cycle will return to normal. However, in rare cases, even after clinical treatment, there is no improvement in the menstrual flow, so this kind of patient is not suitable for contraception with the IUD, and the IUD can be removed and another method of contraception can be used.
