Find out the gender of the unborn baby by the dates of birth of the parents. The calculations use a method that was popular with our grandmothers: the method of renewing the parents' blood. A convenient calendar allows you to immediately get a forecast for the entire period of the mother's childbearing age.
Please note that the method used to determine the gender of a baby does not have any scientific justification or any official recognition in medical practice. Nevertheless, in most cases, the calculation result is accurate.
