Abortion can be done in about one month of pregnancy, but before doing abortion, it must be checked by ultrasound: 1) to determine intrauterine pregnancy; 2) to see the yolk sac in the gestational sac; 3) to match the number of days of menopause with the size of the gestational sac; 4) if the embryo is considered to have stopped developing, it must cause high vigilance in the clinic, because doing abortion after the embryo has stopped developing may lead to coagulation dysfunction The possibility of clinically significant bleeding may be caused. Therefore, if you want to terminate the pregnancy, you must first do the appropriate clinical examination and then decide whether you can do abortion according to the results. In case of painless abortion, an appointment needs to be given first. If it is a normal abortion, the procedure can be done directly after passing the examination.
