For those friends who experience spotting in the first three months of pregnancy, it is very important to know the causes of spotting in the first three months of pregnancy. So what are the causes of spotting in the first three months of pregnancy? Next, this article will introduce the four major reasons for spotting in the first three months of pregnancy, for your reference only. Friends who want to know the reasons for spotting in the first three months of pregnancy can take a look.

What are the reasons for spotting during the first three months of pregnancy? There are four main reasons for spotting during the first three months of pregnancy:

1. Spontaneous abortion

If the embryo itself has defects, it will be eliminated when it develops to a certain extent, and miscarriage usually occurs around 2 months of pregnancy. Early miscarriage (before 16 weeks of pregnancy) is almost always caused by a defect in the fertilized egg, resulting in abnormal fetal development, and is often unavoidable. When an embryo dies in the womb, it is often accompanied by vaginal bleeding.

2. Lack of progesterone

If the pregnant mother lacks progesterone, a small amount of vaginal bleeding will occur. The amount of blood is less than the menstrual volume and the blood is bright red. The early pregnancy reaction still exists, sometimes accompanied by mild lower abdominal pain, back pain and a feeling of falling. During the three months of pregnancy, the ovaries will form a corpus luteum to maintain the supply of nutrients. After 3 months of pregnancy, the placenta slowly forms. When the corpus luteum of pregnancy slowly shrinks and the placenta has not yet formed, the lack of progesterone can easily lead to a gap in nutrition and inability to meet the fetus's needs.

3. Subchorionic blood clot

When a pregnant woman has a blood clot under her chorion, the amount of bleeding in her private parts may vary. This is because the blood clot is formed by coagulation in the uterus, so the blood clot is brown in color. Blood clots appear under the chorion of the pregnant mother. This is because the chorion that wraps the fetus (the intrauterine villi that form the placenta) is slightly separated from the uterine wall, and blood clots will form on the outside, causing bleeding in the pregnant mother. At this time, the nutritional supply required by the embryo will also be affected.

4. Hydatidiform mole

Pregnant women often have heavy intermittent vaginal bleeding. If white, transparent, grape-like blisters are discharged, the diagnosis can be confirmed. Moreover, the early pregnancy reactions are severe, the level of human chorionic gonadotropin is particularly high, and the size of the pregnant mother's uterus is larger than that of a normal pregnancy month.

The above is an introduction to the reasons for spotting in the first three months of pregnancy. I believe that after reading the above introduction, you already know the reasons for spotting in the first three months of pregnancy. Therefore, for friends who experience symptoms such as spotting in the first three months of pregnancy, they must go to the hospital for treatment in time!
