Usually, most women get their period around 30-40 days after a medical abortion. However, since medical abortion is harmful to the body and the recovery of the body varies from person to person. Therefore, if a woman does not have a period after a month of medical abortion, she can observe for about 10 days, probably due to the slow recovery of her body. If after 10 days there is still no menstruation, it is recommended that women immediately consult a doctor for targeted treatment according to the cause. Specific causes and treatment 1. Endometrial damage: When a patient chooses to have a medical abortion, the drug causes the placenta to shed causing damage to the endometrium, which usually results in normal menstruation 1-2 months after the abortion, and the degree of endometrial damage and repair can be assessed by ultrasound testing. If the damage is mild and is being repaired, the patient does not need to worry too much at this time. When the endometrium is repaired, menstruation will come naturally and the vaginal ultrasound can be reviewed regularly. If the damage is more serious and the repair is slow, it is recommended to take oral estrogen drugs to promote the recovery of the endometrium as prescribed by the doctor. 2. Uterine cavity residues: When the patient uses drug abortion incompletely, the residual tissue causes adhesions in the cervix, which may result in the inability to discharge menstrual blood, manifesting as menstrual failure, and the patient may be accompanied by abdominal pain, fever and other symptoms. Vaginal ultrasound can be performed to confirm the diagnosis and clear the uterus in time for treatment; 3. Pregnancy again: If the patient has sex within one month after the medical abortion and there is no effective contraception, the possibility of pregnancy again cannot be ruled out, and the pregnant woman is advised to go to the hospital for blood HCG examination. Generally speaking, the uterus has not fully recovered after the medical abortion, and it is usually recommended to have another pregnancy after six months. However, if there is a pregnancy condition, it is necessary to decide whether to terminate the pregnancy according to the doctor’s advice; 4. Endocrine disorders: poor sleep, infection, emotional disorders and other factors lead to disruption of functional hormone secretion and menstrual disorders, which can be manifested as no menstruation after one month of medical abortion, patients can help the recovery of menstruation by changing their habits, calming their mind and regulating endocrine. Certain disease factors, such as thyroid abnormalities and ovarian hypofunction, can lead to organic endocrine disorders, resulting in the absence of menstruation, accompanied by corresponding symptoms, such as weight loss, increased frequency of stool, vaginal dryness, etc., which require timely consultation and causal treatment. Patients should get enough rest and adjust their mindset after the abortion. At the same time, pay attention to the repair of the uterus and the normal nature of vaginal discharge. If there is any abnormality, it is recommended to seek medical attention in time.
