The earliest you can abort a pregnancy is around 40 days, because the pregnancy is too young for the gestational sac to reach the uterine cavity. In general, most of the gestational sacs enter the uterine cavity around 40 days after menopause, but before abortion, a routine ultrasound should be performed to understand the size of the gestational sac and the location of the bed. If the gestational sac is too small, it will easily cause leakage and incomplete aspiration, so abortion should not be performed too early. If the ultrasound indicates that the gestational sac is in the uterine cavity around 40 days, some tests should be routinely performed before the abortion, such as routine leukorrhea, routine blood tests, infectious diseases, electrocardiogram, etc. If there is no abnormality, the patient can choose abortion or drug abortion to terminate the pregnancy.
