The first abortion of a woman causes harm clinically with inflammation of the reproductive tract, such as causing inflammation of the cervix, inflammation of the endometrium, inflammation of the pelvis, which can cause increased vaginal discharge, repeated lower abdominal pain, and can even lead to infertility. In the vast majority of cases, if the abortion is followed by strict medical advice, it will not lead to inflammation, and it is also recommended to take oral antibiotics for 2-3 days after the abortion, mainly to prevent infection. Damage to the reproductive tract, if the endometrium is damaged during the abortion, it will cause adhesions in the uterine cavity, causing amenorrhea or a significant reduction in menstruation, which requires hysteroscopy to separate the adhering tissues before menstruation can be expected to resume, and the above are the dangers of abortion.
