The best time to have an abortion is 35-70 days after menopause if the menstrual period is usually regular, about once in 28 days, because the gestational sac at this stage is between 1-3 cm, which is easier to clear at once, and at the same time, the length of the embryo at this stage is usually not more than 2 cm, which will take less time, and the bleeding and the impact on the uterus will be smaller. However, it should be noted that an ultrasound should be done before the abortion is performed, on the one hand, to determine whether the pregnancy is intrauterine or ectopic, and only patients with intrauterine pregnancy can have an abortion. On the other hand, it is necessary to check the size of the gestational sac and the length of the germ, and only patients who meet the requirements can be considered for abortion to avoid uncontrollable risks that may affect the patient’s prognosis. After abortion patients must pay attention to rest, avoid lifting heavy objects and overexertion, and be alert for abnormal vaginal bleeding.
