Pregnancy menstruation refers to the period that occurs after a woman becomes pregnant. Nowadays, many women have experienced pregnancy menstruation, which is not actually menstruation, but bleeding in the vagina after pregnancy. If you discover that you are pregnant but your period is approaching, you must be particularly vigilant and it is best to go to the hospital for a check-up. So what is the menstrual cycle during pregnancy?
1、 What is pregnancy menstruation
Pregnancy menstruation, as the name suggests, refers to the menstrual period that occurs during pregnancy. However, the menstrual cycle during pregnancy is not a normal physiological period, but rather refers to a small amount of bleeding during the first three months of pregnancy. Many women are unaware of their pregnancy due to menstrual bleeding during pregnancy.
Modern medicine believes that the chorionic gonadotropin produced by pregnant women cannot convert the corpus luteum of the ovary into the corpus luteum of pregnancy, and the ovarian function continues to be active, resulting in monthly small amounts of vaginal bleeding. After 3-4 months of pregnancy, sex hormones are secreted by the placenta to replace ovarian function. So there will no longer be periodic bleeding.
Women will not experience menstruation again after pregnancy. But a small number of women still experience vaginal bleeding on the scheduled date of their next menstrual cycle after pregnancy. At this time, pregnant women often mistake it for menstruation and are unaware that they are pregnant. This situation that occurs after pregnancy is called "pregnancy menstruation".
2、 What's wrong with pregnancy menstruation
There may be slight bleeding during implantation of the fertilized egg, and the bleeding time generally does not exceed 3 days. In addition, there is generally no vaginal bleeding during pregnancy, otherwise threatened miscarriage, ectopic pregnancy, and other possibilities need to be considered. Generally speaking, the reasons why vaginal bleeding is more common in early pregnancy are as follows:
1. Physiological bleeding: After conception, some women may still experience a small amount of bleeding during the same month, usually without other accompanying symptoms (such as abdominal pain and menstrual discomfort). This may just be a physiological response to the implantation of the fertilized egg. This condition does not require treatment, as long as the external genitalia is kept clean.
2. Miscarriage: When the decidua of the uterus bleeds, it separates the placenta from the uterine wall and stimulates the uterus, causing it to contract, the cervix to dilate, and blood to flow out of the uterus. This type of bleeding is often accompanied by lower abdominal pain, with the amount of bleeding increasing from less to more, the color changing from dark to red, and the abdominal pain gradually developing from dull to more severe.
3. Ectopic pregnancy: When the fertilized egg develops to a certain extent, it can cause the fallopian tube wall to rupture and bleed. Due to this type of bleeding flowing inside the abdominal cavity, vaginal bleeding may not be significant. But this kind of blood loss often leads to fainting, shock, etc. If not treated in a timely manner, it can cause the patient's death.
4. Molar pregnancy: molar miscarriage usually begins 2-3 months after amenorrhea. Bleeding is often intermittent with small amounts, but some may have repeated episodes of heavy bleeding.
5. Overwork: If pregnant women are overworked and under high work pressure in the early stages, it may also cause slight vaginal bleeding, so they should go to the hospital for examination in a timely manner.
Through the introduction in this article, it can be known that menstrual bleeding during pregnancy is not actually menstruation. It may be a normal physiological bleeding or an abnormal bleeding. So if you experience menstrual bleeding during pregnancy, it's important not to underestimate it. It's best to go to the hospital for a check-up.
