The situation is somewhat different if the test does not reveal pregnancy, when there are signs of conception and menstruation has not come.
Girls may feel dizzy and nauseous, vomiting reactions or mammary glands, mood swings and drowsiness, but testing gives a negative result.
In such a situation, the specialist recommends that patients re-diagnose after one week.
It is better to use express tests from different manufacturers, and if they do not help clarify the problem, then donate blood for chorionic gonadotropic hormone. Why does the test not show pregnancy? There can be many reasons for false negative test results.
• If a girl's menstruation comes irregularly, then the probability of false-negative test results increases significantly, because it becomes impossible to diagnose pregnancy after a delay in the first days. To maximize the reliability of the results, it is recommended to wait, and after a few days to re-test
• Also, the false positive nature of the test data, when the delay is a week, and the test is negative, is possible if the patient consumed a lot of water on the eve of the diagnosis. Because of this, the urine becomes dilute, so the hCG concentration in it drops so much that the test reagents do not recognize the presence of a hormonal substance in the urine.
• Quite often similar situations with diagnostics arise in the presence of hepatic pathologies or serious failures in urinary activity.
• Also, a factor explaining why the test does not show pregnancy, but there is no menstruation, may be a banal non-compliance with the instructions for using the express test or improper storage.
In the event of such situations, the most correct solution would be to consult a gynecological and endocrinological specialist or a therapist.
