It is not mandatory to take oral Yusui (drospirenone ethinyl estradiol tablets (II)) for three months after miscarriage, but it is recommended to take it for 3~6 months. On the day of abortion, clinicians often recommend oral short-acting contraceptives for 3 to 6 months to repair the uterine lining, prevent uterine adhesions, regulate the menstrual cycle, and can also be taken for a long period of time if there is a need for contraception. After abortion, menstrual cycle disorders can easily occur, and getting pregnant again a short time after abortion is also very harmful to the human body, so those who have no contraindications are recommended to take short-acting contraceptives orally for 3 to 6 months. There are risks of incomplete abortion, uterine adhesion and secondary infertility during and after abortion, so if you don’t have a need for childbearing, we recommend that you use scientific contraception to avoid harming your body.
