From the first day of the delay, it is quite acceptable to do a test, and the results of such a diagnosis are most often reliable. Among the common reasons for the absence of menstruation, which are not due to pathological conditions, are a lot of various factors. The most common is considered to be a stressful effect, for example, lack of sleep or emotional experience, changes in climatic conditions or increased stress - all this can provoke a stressful condition that will affect the regularity of menstruation and the days of their onset.
Also, a violation in the diet, more precisely, a deficiency of micronutrients and vitamin substances entering the body, can also lead to the absence of menstruation. Sharp fluctuations in weight always negatively affect the regularity of the female cycle.
Hormonal imbalances, taking or suddenly stopping contraception, the use of emergency contraceptives and the onset of menopause and other hormonal abnormalities also often lead to regulatory failures.
In this clinical case, it does not matter on which day of the delay the tests show pregnancy, because conception is absent with pathological and physiological delay factors.
Regulations may be delayed if the patient has any internal pathology of a cold, kidney disease or gastritis, endocrine abnormalities or pneumonia, cerebral pathologies, etc. Even taking drugs from the group of neuroleptic drugs can cause menstrual failure.
Although these factors are physiological in nature, many of them are dangerous and have an extremely negative effect on the female body.
