If a woman uses a pregnancy test stick to detect two bars, one deep and one shallow, it means that she is pregnant, but because it is one deep and one shallow, the pregnancy condition is not very stable. But later on, menstruation occurred again. This situation suggests that the woman may have had a miscarriage. This situation is called biochemical pregnancy.
What is the reason for measuring the depth and depth of menstruation?
A few days ago, the early pregnancy test strip tested two red lines, one deep and one shallow. Today is my menstrual period. It may be due to a biochemical pregnancy. Biochemical pregnancy is a disease caused by the failure of fertilized egg implantation. The clinical manifestation is delayed menstruation followed by vaginal bleeding similar to menstruation. Early pregnancy test strips may show weak positive results. No damage to the uterus. Don't worry too much.
What is biochemical pregnancy?
Biochemical pregnancy refers to the union of sperm and egg. Generally, seven days after the union, the secretion of chorionic gonadotropin is required. After another seven days, it can be detected using early pregnancy test strips. Often, the sperm and egg have combined and secreted, but they must combine to form a fertilized egg. The fertilized egg still needs to return to the uterus for implantation. Biochemical pregnancy refers to the union, but it has not returned to the uterus for implantation, or has returned without getting into bed. This is called biochemical pregnancy.
The main causes of biochemical pregnancy
1. The fertilized egg itself has defects;
2. Ovarian corpus luteum dysfunction, insufficient progesterone secretion, abnormal endometrium, affecting the implantation of fertilized eggs;
3. Uterine factors: uterine dysplasia, submucosal fibroids, endometrial polyps, intrauterine adhesions, endometrial tuberculosis, and other factors that affect the implantation of fertilized eggs;
4. Immune factors: In recent years, research on immune factors suggests that there are two immune conditions that can affect fertility. Same type immunity: Sperm, seminal plasma, or fertilized egg are antigenic substances that are absorbed by the vaginal and uterine epithelium, and produce antibody substances through immune reactions, preventing sperm and egg from binding or preventing fertilized egg from implanting; Autoimmunity: It is believed that there are autoantibodies against the zona pellucida in the serum of infertile women, which can react with the zona pellucida to prevent sperm from penetrating the egg and thus prevent fertilization;
5. Traditional Chinese Medicine Rehabilitation: If all the above tests are normal, it is necessary to see if traditional Chinese medicine can detect any problems;
6. Excessive mental stress, especially severe anxiety and psychological pressure due to not being pregnant.
This article provides a detailed explanation of what happens when menstruation occurs despite measuring two bars, one deep and one shallow. It also explains what biochemical pregnancy is and the reasons for it. As a woman, if you encounter the situations described in this article, it is best to refer to the content of this article.
