The “period” is also known as menstruation. Normally, the recovery time of menstruation after abortion is about 4-6 weeks, but there are differences in the recovery time of menstruation after abortion due to individual’s physical condition, uterus and ovaries. After an abortion, the hormones and reproductive organs in the body will change, and in general, the ovaries resume ovulation about 2-3 weeks after the abortion. At the same time, the corpus luteum grows and matures and begins to secrete progesterone and estrogen, causing the endometrium to begin to thicken periodically, and the endometrium is shed about 2 weeks after ovulation to form menstruation. Therefore, under normal circumstances, menstruation will resume about 4-6 weeks after abortion. If menstruation does not resume after 6 weeks of abortion, firstly, we should rule out the possibility of another pregnancy, then consider pathological problems such as endometrial damage, endocrine disorder, uterine adhesions, etc. It is recommended to go to the hospital for hormone 6, ultrasound and other related examinations as soon as possible to clarify the reasons for not getting menstruation and treat the symptoms.
