Can Biochemical Pregnancy Be Detected Using an Early Pregnancy Test?

A pregnancy test strip cannot detect biochemical pregnancy. It is necessary to undergo a blood HCG test at the hospital to determine whether the HCG level has increased and whether the increased level is normal. Therefore, if the test strip does not darken after several uses, it is recommended to promptly visit the hospital for examination to confirm whether the pregnancy status is normal. Biochemical pregnancy refers to an early miscarriage that occurs within 5 weeks of pregnancy, that is, the fertilized egg is lost before implantation. An increase in human chorionic gonadotropin can be detected in the blood, or a positive result can be observed on a urine pregnancy test. If it is a normal pregnancy, testing with a pregnancy test strip every other day will show a significant darkening of the second line. However, if there is no darkening after several tests, it may indicate biochemical pregnancy, and further examination at the hospital is required.

1. It is generally believed that the causes of biochemical pregnancy are consistent with those of spontaneous abortion. Abnormal embryo chromosome and defects in the fertilized egg may be the main reasons for developmental stagnation.

2. Insufficient progesterone secretion due to luteal phase defect, abnormal endometrial function, and other ovarian dysfunction can affect the implantation of the fertilized egg.

3. Uterine factors such as uterine dysplasia, submucosal myoma of the uterus, endometrial polyps, intrauterine adhesions, and endometrial tuberculosis can also affect the implantation of the fertilized egg.

4. Excessive mental stress, especially severe anxiety due to infertility, can also contribute to biochemical pregnancy. Biochemical pregnancy is a kind of natural selection of survival of the fittest in a certain sense. Women of reproductive age should not panic when encountering such situations, as biochemical pregnancy generally does not affect subsequent pregnancies. However, further examination at the hospital may be necessary if such situations occur repeatedly.
