The test paper showed two lines but no pregnancy

When using a test strip to detect early pregnancy, if the test strip shows two bars, it generally means pregnancy. However, if you are not pregnant and there are two lines on the test paper, it is most likely caused by a biochemical pregnancy. Biochemical pregnancy is an abnormal pregnancy phenomenon, which causes great physical harm to women. Next, I will introduce you to some relevant knowledge about biochemical pregnancy.

1. The reason why there are two lines on the test paper but no pregnancy

There is no obvious history of amenorrhea, but the early pregnancy test showed two bars. This could be a biochemical pregnancy, meaning that fertilization has just occurred and the fertilized egg has not yet had time to enter the uterus, but it dies on its own. Vaginal bleeding is similar to normal menstruation. It is recommended to go to the hospital for a blood hcg check one week later.

What is biochemical pregnancy?

Biochemical pregnancy refers to the secretion of human chorionic gonadotropin after the combination of sperm and egg, but the fertilized egg does not implant in the uterus and the pregnancy is not successful. Generally, human chorionic gonadotropin will be secreted 7 days after the sperm and egg combine, and it can be detected with an early pregnancy test after another 7 days. Biochemical pregnancy usually occurs within 5 weeks of pregnancy, also known as subclinical miscarriage, and is more common in in vitro fertilization.

The main causes of biochemical pregnancy

What are the causes of biochemical abortion and factors that affect the implantation of fertilized eggs:

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

2. Poor ovarian corpus luteum function, insufficient progesterone secretion, and abnormal endometrium affect 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, 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; (blood test to check immune antibodies and blocking antibodies)

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

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