It is better to have an abortion within 45-60 days of pregnancy because at this time the size of the gestational sac is more moderate, the yolk sac can be seen and even the fetal bud can be seen, and the abortion is less harmful to the woman, so abortion is usually performed within 45-60 days of menopause. Before the abortion, some tests should be performed, such as routine white belt examination, routine blood test and examination of infectious diseases, including syphilis, hepatitis C, hepatitis B, AIDS and so on. If the abortion is painless, it is recommended that an electrocardiogram be performed, and if there is no abnormality, the abortion can be performed routinely.
