Forty-four days after abortion, she didn't have her period.

Irregular menstruation after abortion is a normal phenomenon. It may be caused by deficiency of qi and blood, or it may be caused by the endometrium that has not been repaired yet. You can go to the hospital for a uterine B-ultrasound to observe the growth of the endometrium. If the endometrium is too thin, you can take estrogen drugs orally to promote endometrial hyperplasia.
