Will the second menstrual period be delayed after abortion?

After an abortion, if you have a menstrual period and your second period is delayed, you should first check whether you are pregnant. If the menstruation is delayed within seven days, it is normal. However, if the menstruation has not come for more than seven days and pregnancy has been ruled out, it may be caused by endocrine imbalance.

If abdominal pain or a small amount of vaginal bleeding occurs, it cannot be ruled out that it is adhesion of the uterine cavity or adhesion of the cervical canal. You should go to the hospital for B-ultrasound as soon as possible to observe whether there is blood accumulation in the uterine cavity.

If there is blood accumulation in the uterine cavity, it may be due to uterine adhesion or cervical adhesion, which causes delayed menstruation. It may also be caused by endocrine imbalance. Treatment should be carried out according to the examination results.

Reasons for delayed menstruation after abortion

1. Because menstruation is regulated by neuroendocrine system, it is the result of the interaction between the cerebral cortex, hypothalamus-pituitary gland, pituitary gland, uterus and ovaries, so when women are too anxious, afraid, sad, overworked and undergoing surgery, the neuroendocrine system can inhibit the functions of the hypothalamus-pituitary gland, pituitary gland, uterus and ovaries, leading to irregular menstruation.

2. The reason for abnormal menstruation after abortion is that during the abortion process, the dermis of the female uterine wall is excessively damaged, making the uterine wall unable to regenerate. In this case, women will experience irregular menstruation, and in severe cases, they may suffer from long-term amenorrhea.

3. Frequent abortions. Some women have several abortions in a year. The uterine wall is scraped and thinned, and cannot be repaired in a short period of time, which leads to abnormal menstruation after abortion.

4. After an abortion, the fetal human chorionic gonadotropin suddenly disappears, causing the uterus and ovaries to temporarily fail to respond to the gonadotropin secreted by the anterior pituitary gland, which leads to irregular menstruation in women.

5. Having sex or taking a sitz bath too soon after abortion. Some women have sex with their husbands a few days after surgery or take a sitz bath without following the doctor's advice, which causes bacteria to invade the vagina and uterus, leading to intrauterine infection and irregular menstruation.
