Will taking a double dose of contraception weaken its effectiveness?

To @Oliwia: There is no reason to worry, just taking a double dose of hormones for 3 days will not weaken their contraceptive effect. Effectiveness is preserved. Please continue to use the tablets - further already 1 a day at the same time.

These are Slinda tablets

The tablets were taken at the correct time, the next I accepted unfortunately because of my assumptions I treat myself with a psychologist, so also such a procedure.

Taking the second ("extra") tablet was caused by some event, e.g. severe vomiting or diarrhea up to 3-4 hours after taking the tablet? If so, if the extra tablet has been taken up to 12 hours after the time the tablet is routinely taken, the protection against pregnancy has been preserved. If the break was longer, an additional method of contraception in mechanical form (e.g. a condom) should be used for 7 days after the event. If all 3 tablets were taken later and the standard ones were not taken, you should consult a gynecologist. Below is a link where you can have an e-visit with a gynecologist (and another specialist): https://www.gdziepolek.pl/telekonsultacja

I took the tablets normally at such an hour as always, but the second dose later, so I ask about the effectiveness

I have additional packaging

These are one-component tablets , in the first week of the blister
