Do stream of people to do not have menses normally

Menstruation usually occurs within 25 to 35 days after abortion, and the longest period will not exceed 40 days. If menstruation does not occur for a long time, it may be caused by poor uterine recovery, endocrine disorders, endometritis and intrauterine infection. Sex hormones and uterine color Doppler ultrasound should be admitted to hospital.
