Abortion is relatively harmful, especially if it is repeatedly performed, which is harmful to women’s body, uterus and endometrium. If a woman’s uterine lining is relatively thin, a single miscarriage may cause damage to the endometrium and cause menorrhagia and even infertility. Therefore, if a woman does not intend to have children, she should do a good job of contraception, taking oral contraceptives or intrauterine devices such as the IUD for effective contraception. The abortion should be carried out in a regular hospital, avoiding small clinics, otherwise it may cause lifelong damage to the woman’s body.
