What is the difference between pregnancy bleeding and menstruation?

Menstruation is a physiological phenomenon that women face every month, and its main manifestation is uterine bleeding. And during pregnancy. Especially in the early stages of pregnancy, many pregnant women will experience bleeding, which is mainly caused by abnormal fetal development, low maternal immunity, viral infection, excessive stress, excessive sexual life and other reasons. Many women who don't know they are pregnant often mistake it for their period. In fact, there is still a big gap between the two.

That is menstruation. Menstruation is a physiological cycle that occurs in some fertile women. About once a month, the endometrium of women of childbearing age undergoes cyclical changes including autonomous thickening, blood vessel proliferation, glandular growth and secretion, and endometrial collapse and shedding accompanied by bleeding. This periodic vaginal discharge or uterine bleeding is called menstruation.

The main components of menstruation are blood (3/4 arterial blood, 1/4 venous blood), endometrial tissue fragments and various active enzymes and biological factors. Among them, fibrinolytic enzyme makes menstrual blood liquid and prevents it from coagulating, and prostaglandins play the role of contracting the uterus.

The difference between pregnancy bleeding and menstruation

1. Bleeding during pregnancy is a threat of miscarriage, so you must seek medical attention as soon as possible.

2. Menstruation is caused by the shedding and bleeding of the endometrium due to lack of conception.

3. Bleeding in early pregnancy is sometimes caused by the embryo implanting and growing into the inner wall of the uterus. The bleeding caused by this process is very small. Sometimes it's like dark vaginal discharge.

4. If it is a threatened miscarriage, there may be a problem with the embryo growing into the inner wall of the uterus, or there may be corpus luteum insufficiency. There are many possibilities. The amount of bleeding will become heavier, like menstruation, with some bleeding being less than menstruation and some being more than menstruation. You need to see a doctor as soon as possible.
