The first of these is the fact that the company’s business is not a good one. Second, gastrointestinal factors: some women vomit after taking abortion drugs because of gastrointestinal reactions, and poor drug absorption can also affect the efficacy of the drug, resulting in incomplete medical abortion. A week after the abortion, go to the hospital in time to review the ultrasound to understand whether there is residual in the uterine cavity. If the amount of residual in the uterus is not too much, you can continue to take oral blood circulation and blood stasis medication to promote the discharge of blood and residual tissue in the uterus, and if necessary, perform a timely clearance operation to avoid residual tissue in the uterus for too long, which is not easy to remove after mechanization and causes damage to the endometrium of the woman’s uterus.
