Is it normal that after using Ginoring without a week's break, menstruation can be delayed?

The "combination" of Ginoring packaging, i.e. the use of two discs in a row, should not affect the appearance of withdrawal bleeding. According to the documentation of this drug in the section on how to delay the onset of bleeding: "Although it is not recommended, it is possible to delay the onset of menstruation (withdrawal bleeding) by setting up a new vaginal therapeutic system immediately after removing the previous one, without a period of interruption in its use. The new vaginal therapeutic system can be used for no more than 3 weeks. During the period of use of the new vaginal therapeutic system, spotting (single drops or blood stains) or mid-cycle bleeding may occur. In order to induce withdrawal bleeding, the vaginal therapeutic system should be removed. A regular weekly break between systems is recommended. Before you decide to delay the onset of bleeding, you can ask your doctor for advice." Sometimes withdrawal bleeding may not occur despite the absence of pregnancy. If you are concerned or something happened during the use of the method that could affect its effectiveness - you can perform a pregnancy test.
