How long it takes to get menstruation after abortion depends on individual’s physical condition, hormone level, uterus and ovary recovery, etc. Normally, menstruation can be restored in 4-6 weeks. Abortion, i.e. the termination of pregnancy by surgery or medication, can have certain effects on a woman’s body, such as damage to the endometrium and endocrine disruption, and it takes time for all organs to recover. The ovaries stop ovulating during pregnancy and the corresponding endometrium stops thickening and shedding. After an abortion, the ovaries can resume ovulation in about 2-3 weeks with the re-stimulation of various hormones, and the endometrium also starts to thicken in a new cycle, and can shed about 2 weeks after ovulation to form menstruation. Therefore, under normal circumstances, a woman resumes menstruation about 4-6 weeks after an abortion. If there is no menstruation for more than 6 weeks after abortion, the cause needs to be checked at the hospital and then treated accordingly. In addition, the patient’s body is weak after abortion, so it is necessary to pay attention to the intake of highly nutritious food and to rest in order to promote the body to recover as soon as possible.
