It is normal for women to have pregnancy vomiting after an abortion because it will only end 2-3 days after the abortion procedure. The reason why women experience pregnancy vomiting is mainly influenced by the elevated human chorionic gonadotropin in the body. The hormone will only drop significantly 2-3 days after the abortion and the phenomenon of pregnancy vomiting will slowly disappear. If a woman experiences pregnancy vomiting, the possibility of incomplete abortion or missed aspiration cannot be ruled out. It is recommended to go to the hospital for an ultrasound examination to understand the situation inside the uterine cavity and to check whether there is a possibility of incomplete abortion or missed aspiration.
