35-55 days of pregnancy is the best time for abortion because at this time the embryo is still very small, the uterine wall is still thick, the gestational sac can be easily suctioned out, there is less bleeding, and the damage to the uterus is relatively small. Generally, abortion can be performed within the third month of pregnancy if you are in good health. But after the third month, when the embryo develops and grows, the fetal skeleton is formed, and the uterine wall becomes thin, it is necessary to do induced abortion, this kind of surgery has more bleeding, big damage to the uterus, and heavy damage to the mother. Therefore, after an unwanted pregnancy, to determine the termination of pregnancy to choose the best time for surgery, do not delay the best time, unnecessary damage to the body. Women must do a good job of contraception to prevent unwanted pregnancy and protect themselves if they are not sure they want to have a child.
