What are the symptoms and manifestations of biochemical pregnancy

When it comes to biochemical pregnancy, many people don’t know what it means, because in the general perception of people, female pregnancy is a very normal and natural thing, and no special circumstances will occur. Biochemical pregnancy means that after the sperm and egg combine, they do not develop normally and swim into the uterus, but instead are lost along with the woman's menstruation. So what symptoms will appear to know that a biological pregnancy has occurred?

Early symptoms of biochemical pregnancy

1. Biochemical pregnancy is a phenomenon in which the sperm and egg fail to implant after combination and are lost along with menstruation. Generally, it will disappear naturally within 50 days. Since it occurs in early pregnancy, what symptoms can be used to determine early that it is a biochemical pregnancy?

2. After the sperm and egg combine, they implant in the uterus. Generally, a weak positive reaction will be detected using an early pregnancy test paper around 14 days later. Under normal circumstances, it will deepen to a strong positive day by day, while a biochemical pregnancy will only fade day by day and it is impossible to reach a strong positive.

3. Some people with biochemical pregnancy will feel obvious abdominal pain, and the degree of abdominal pain varies from person to person. Some people will have persistent abdominal pain, while a considerable number of people will only have short-term abdominal pain. Some people also experience symptoms of lower back pain. Most people have no symptoms at all.

4. Therefore, we can only rely on some medical data to confirm the diagnosis. During a normal pregnancy, the blood HCG value will double every other day. The better the doubling rate, the better the embryo is developing. If it is a biochemical pregnancy, the blood HCG value will be very low, and it is even less likely to double. Moreover, the gestational sac will not be seen through B-ultrasound examination.

Causes of pregnancy

1. Embryonic factors:

If the embryo itself is of poor quality, it will naturally be eliminated. The quality of the embryo directly depends on the egg and sperm. The quality of these two is actually related to our daily living habits. For example, smoking, drinking, staying up late, overwork, etc. will affect its quality.

2. Ovarian corpus luteum function factors:

A poor corpus luteum will lead to insufficient progesterone secretion and endometrial abnormalities, which will affect the implantation of the fertilized egg in the uterus.

3. Uterine factors:

Uterine hypoplasia, submucous uterine fibroids, endometrial polyps, intrauterine adhesions, endometrial tuberculosis, etc. can all affect the implantation of the fertilized egg.
