How can menstruation still occur after pregnancy? What factors cause menstruation during pregnancy

After pregnancy, women's ovaries do not ovulate, and women also do not menstruate. If menstrual problems occur during pregnancy, they should choose a regular hospital for treatment to prevent maternal accidents.

What is menstruation during pregnancy?

1. Vaginal bleeding

Discovering vaginal bleeding after pregnancy may be a gynecological disease complicated by pregnancy, such as cervical polyps, cervical cancer, and cervical erosion. Some women experience vaginal bleeding as a normal physiological phenomenon.

2. Threatened abortion

If a woman is confirmed to be pregnant in the hospital but experiences vaginal bleeding accompanied by low back pain and pain, attention should be paid to whether threatened miscarriage has occurred and promptly seek medical examination and diagnosis at a reputable hospital.

3. Physiological bleeding

Some women experience a small amount of vaginal bleeding in the first three months of pregnancy, so there's no need to worry. This is a reaction that occurs after the implantation of a fertilized egg. Implantation bleeding occurs after the fertilized egg enters the uterus, and generally does not occur after 3 months of pregnancy.

4. Ectopic pregnancy

If a woman experiences symptoms of vaginal bleeding after about 40 days of stopping menstruation, she often believes that her menstrual cycle is coming. At this time, she must pay attention to her physical condition. If there is ectopic pregnancy due to abdominal swelling, pain, or pain, she needs to go to the hospital for ultrasound diagnosis.

5. Unstable implantation of fertilized eggs

Menstruation mainly refers to a symptom formed by the necrosis and shedding of the endometrium in women, which prepares them for future pregnancy. However, after the fertilized egg is implanted, the endometrium will not fall off. If bleeding occurs after pregnancy, the implantation of fertilized eggs may become unstable. Women who have not yet formed the uterus and placenta are approaching the day of menstruation, when mature eggs are expelled, the endometrium falls off, and the uterus is expelled from the body, which is a symptom of menstrual cycle during pregnancy.

6. Endometrial exfoliation

Because everyone's body is different, after pregnancy, both progesterone and estrogen are very low, the endometrium falls off, and menstruation also occurs. However, at this time, the menstrual flow is relatively low. When the placenta forms 3 months later, the body's pregnancy hormones and estrogen remain at high levels, and menstruation will not occur.

What to do with menstruation during pregnancy

When women experience symptoms resembling menstruation during pregnancy, they should first not be nervous. They should carefully observe the color, volume, or taste of their menstrual period. If there is no pain in the lower abdomen, treatment is not necessary. They should rest more, avoid vigorous exercise, and pay attention to balanced nutrition. However, if abdominal pain is unbearable and falls, timely treatment should be sought from a reputable hospital to identify the true cause of the bleeding and provide targeted treatment.
