The uterine cavity may also become adhesive after the sterilization ring is placed in the abortion. After having an abortion, it will cause some damage to the uterine lining, and if a bacterial infection occurs, the uterine cavity may still have adhesions when the birth control ring is placed in this state. After the abortion, you can put the IUD after a period of time, such as the 3rd-7th day after the first period after the abortion, check that there is no infection and then put it to avoid the occurrence of uterine cavity adhesion. After abortion, you must take anti-inflammatory drugs and drugs to promote uterine contraction as prescribed by the doctor to avoid infection and prevent uterine adhesion. If uterine adhesion has already occurred, it is recommended to go to a regular hospital for surgical treatment to separate the adhesive parts, and also cooperate with the doctor to put the birth control ring, which can avoid the recurrence of uterine adhesion.
