A period after an abortion does not mean that the abortion is clean. It should depend on the menstrual condition and the results of the review. The recovery time of menstruation after the operation is one month, and the length of menstruation will also be determined according to the cycle of each person’s period. If the amount and duration of menstruation when menstruation resumes after the abortion is the same as before the abortion and has not changed, it usually indicates that the abortion has been aborted cleanly. However, if the menstrual period is longer than before or shorter than three days after the abortion, and the menstrual volume is small or very large, it means that there may be an unclean abortion, or poor recovery of the uterus or infection, and you need to go to the hospital for an ultrasound review. Ultrasound is the most accurate way to determine whether there is residue after an abortion, so it is recommended to go to the hospital after menstruation for ultrasound examination. Women after abortion should develop regular habits, do not often stay up late, it is recommended to eat more fresh vegetables and fruits, appropriate supplementation of folic acid and vitamins, and at the same time rest more, avoid overwork.
