Is it a cause for concern if in the next cycle while using Ginoring I did not get menstruation?

There is no rule for the duration and abundance of withdrawal bleeding, although it can be said with certainty that it is less severe than normal menstruation. The symptoms that you have observed are most likely related to the switch of the hormonal axis to contraceptive pills and are typical symptoms occurring in the first month of contraception use (possibly of lesser severity also in the second cycle) and should disappear spontaneously at the next package. If the ailment of similar or greater severity persists in the next cycle, please contact your gynecologist. I enclose a description of the preparation that you use: https://www.gdziepolek.pl/produkty/96195/ginoring-przyrzad/ulotka/244491 I also encourage you to read the article: https://www.gdziepolek.pl/artykuly/jak-prawidlowo-stosowac-antykoncepcje
