50 days after abortion, I haven't had my period yet. What's going on?

If a woman does not menstruate 50 days after abortion, it may be caused by pregnancy. It may also be caused by the presence of residues in the female uterus, suffering from cervicitis, endometrial polyps, endometriosis and other gynecological diseases. Women need to go to the hospital for B ultrasound examination. If the examination results show that there are residues in the uterus, they need to actively do curettage treatment.
