What are the changes in hcg values ​​during biochemical pregnancy?

What is a biochemical pregnancy? A biochemical pregnancy means that the fertilized egg has not reached the uterus or has implanted in the uterus but has not developed. The test paper can detect the pregnancy, but the gestational sac cannot be found in the B-ultrasound examination. It does not cause much damage to the uterus. You can think of it as your menstrual period. So don’t feel too anxious. The hcg value also changes before and after biochemical pregnancy. Let’s take a closer look at it below.

What are the changes in hcg during biochemical pregnancy?

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

2. B-ultrasound cannot see 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.

Biochemical pregnancy is more common during in vitro fertilization. Most women do not go to the hospital for examination and do not pay attention to it, so they ignore it as delayed menstruation. In fact, it is already a natural miscarriage, which is also called hidden miscarriage clinically. Women of childbearing age should not panic if they encounter such a situation. This is the result of nature's elimination and generally will not affect the next pregnancy.

Causes of chemical pregnancy

1. The fertilized egg itself is defective; (check the chromosomes of both parties)

2. Poor ovarian corpus luteum function, insufficient progesterone secretion, abnormal endometrium, affecting the implantation of the fertilized egg; (check six hormone items)

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

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, antibodies are produced through immune response, allowing sperm and egg to combine
