40 days after I have abortion, why don't you menstruate?

After abortion, a month after the general will resume menstruation, if 40 days or no menstruation, pay attention to whether it is pregnant. If pregnancy is ruled out, it may be caused by slow endometrial repair, you can do a color Doppler examination to observe the thickness of the endometrium. If the thickness is 10mm, there is generally no problem, waiting for menstrual cramps.
