Can 2 weeks already be considered a long-term bleeding and should I stop taking Slinda tablets?

You did not say how long you have been using contraception, so it is difficult to propose a specific method of treatment based on such a short description. Any modifications in therapy, including discontinuation of the drug, should be made after consultation with the attending physician acquainted in detail with your state of health. We wrote more about it here: https://www.gdziepolek.pl/artykuly/czy-jak-i-kiedy-mozna-odstawic-leki If you have just started using contraception, the symptoms you feel may be related to the transition of the hormonal axis to the contraceptive pill and are typical symptoms occurring in the first month of use (or less severe also in the second cycle on tablets) and should disappear spontaneously with the next pack. If you have been using Slinda for more than half a year, I encourage you to consult a gynecologist, because any bleeding disorders should be consulted with a gynecologist. If you are unable to get to your doctor, the GdziePoLek.pl service also allows you to obtain a teleconsultation with a doctor: https://www.gdziepolek.pl/telekonsultacja The GdziePoLek.pl service also allows you to book a medicine in the nearest stationary pharmacy and pick up after presenting a prescription: https://www.gdziepolek.pl/produkty/101505/slinda-tabletki-powlekane/apteki
