The appearance of a fuzzy strip on a pregnancy test can be caused by various factors:
• Poor quality product. If the test system has an expired expiration date or was originally produced with a marriage, then a pale second strip is quite possible.
• Diagnosis was performed too early. The annotation for each test clearly states that it is recommended to conduct a study no earlier than after a delay is detected. It is on these days of the cycle that the gonadotropic chorionic hormone will be released in sufficient quantities to be detected. Hypersensitive test systems are able to recognize the presence of hCG as early as a week and a half after fertilization, but at the same time, a pregnancy test will show a pale stripe.
• Implantation failed. The strip does not appear in full force if the fetal egg is not sufficiently fixed to the endometrial layer, or was completely rejected. Under such conditions, the hCG content will be too low for a given gestation period. Therefore, a fuzzy second strip appears, it is pale and, as it were, smeared. If gestation is interrupted, then re-diagnosis will give a negative result.
• Misinterpretation of results. Sometimes girls literally rave about the idea of getting pregnant and manage to look out for two strips in an absolutely negative test. Indeed, upon careful examination of the indicator sector, you can see a faint strip on the pregnancy test, it is barely visible, but still visible. This situation does not mean the presence of pregnancy, but only indicates the place of the likely manifestation of the second band.
• Hormone-producing tumor formations. These can be benign or oncological tumors of the ovaries or the uterine body, liver and other organs that produce female sex hormones, which leads to the appearance of two stripes on the express test.
• Late maturation of the egg. If the ovulatory period occurs at a later time, and not in the middle of the cycle, then the hCG level will also take longer to accumulate, and during testing, two lines will appear, only the second strip is pale.
