It is not normal to have brown discharge 20 days after abortion in general.
In 7-10 days after abortion, there may be a small amount of brown discharge, and if the time is too long, the possibility of poor uterine contraction or residual in the uterine cavity cannot be ruled out. It is recommended that patients go to the hospital in time for ultrasound review to understand the condition of the uterus.
If there is a residue in the uterine cavity, it is necessary to carry out the removal of the uterus in time, or give medication under the guidance of the doctor for oral intake, such as mifepristone, estradiol valerate, progesterone and so on.
It should be noted that after the abortion operation, abstain from sexual intercourse and tub bath for one month. If the vaginal bleeding time is too long, it is recommended to timely review, symptomatic treatment.
