What are the symptoms before biochemical pregnancy?

I don't know if you have heard of the term biochemical pregnancy in your life. Biochemical pregnancy is an abnormal pregnancy, but it is also very common. In fact, this kind of pregnancy does not need to go to the hospital, but can be detected by test paper by itself, because its early pregnancy test paper will have obvious colored bands, which will make pregnant women often feel abdominal pain, which is a manifestation of embryo problems. So what are the symptoms before biochemical pregnancy?

What are the symptoms of biochemical pregnancy

The most direct manifestation of biochemical pregnancy is delayed menstruation, and the use of early pregnancy test paper will detect obvious colored bands, and even the HCG data value during blood test will be greater than 25mIU/mL. A normal pregnancy test strip will continue to darken, and the HCG value will double every other day, which means that the embryo is developing well. In the case of biochemical pregnancy, the HCG value is generally low. When you check again after a few days, the color of the early pregnancy test paper will only become lighter and lighter or even white, and the HCG value will only decrease, which means that there is a problem with the embryo.

Some people 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.

What causes a biochemical pregnancy?

1. The fertilized egg itself is defective;

2. Poor ovarian corpus luteum function, insufficient progesterone secretion, and abnormal endometrium affect the implantation of the fertilized egg;

3. Uterine factors: uterine hypoplasia, uterine submucosal fibroids, endometrial polyps, intrauterine adhesions, endometrial tuberculosis, etc. affect the implantation of the fertilized egg;

4. Immune factors: Research on immune factors in recent years has shown that there are two immune conditions that affect conception. a Alloimmunity: sperm, seminal plasma or fertilized egg are antigenic substances. After being absorbed by the vaginal and uterine epithelium, they produce antibody substances through immune reaction, which prevents sperm and egg from combining or fertilized egg from implanting; b Autoimmunity: It is believed that there are zona pellucida autoantibodies in the serum of infertile women, which react with the zona pellucida to prevent sperm from penetrating the egg, thus preventing fertilization;

5. TCM treatment: If the above tests are normal, see if TCM can find any problems;

6. Excessive mental stress, especially severe anxiety due to failure to conceive, and excessive psychological pressure.

What are the characteristics of biochemical pregnancy

1.ZZY can detect a weak positive, but it is difficult to reach a positive, let alone a strong positive.

2. Ultrasound does not show the presence of a gestational sac in the uterus.

3. A very low blood HCG value only means that you are pregnant, but it cannot indicate whether implantation is successful.

4. Generally, spontaneous abortion will occur within 50 days. A grayish-white film will flow out.
