Relatively speaking, medical abortion is less harmful than surgical abortion, but there is an absolute time requirement for medical abortion, and usually the shorter the time, the better the result. Generally, the success rate of medical abortion is higher within 49 days of menopause, but once the time limit is exceeded, surgical abortion must be used. At around 55 days of pregnancy, abortion is recommended to remove the embryonic sac from the uterus manually using machinery. Both medical and human abortions are more damaging to women, so it is recommended that women seek out a doctor at the hospital and make their choice under the guidance and advice of the doctor. After having an abortion or medical abortion must pay attention to maintenance, otherwise it may leave after-effects.
