When a woman becomes pregnant again after a miscarriage, it depends on the location of the gestational sac, its size, and the woman’s fertility requirements to choose a comprehensive treatment. If a woman becomes pregnant again after a miscarriage, but the gestational sac is growing outside the uterine cavity, this is an ectopic pregnancy, and usually there is no way to continue the pregnancy, so the only option is to consider hospitalization for surgery or medication to kill the embryo. If a woman has an intrauterine pregnancy after miscarriage, but does not have a need to have children, and the gestational sac is under 2 cm, she can consider taking mifepristone and misoprostol for a medication abortion. If the gestational sac has exceeded 3cm but is less than 4cm, only another abortion can be performed to terminate the pregnancy and it is advisable to take drospirenone ethinyl estradiol tablets to promote the repair of the endometrium after the abortion procedure. For women with intrauterine pregnancy, those with fertility requirements can continue the pregnancy, but they must have regular checkups and take folic acid immediately.
