If I have taken the additional Vibin contraceptive pill several times unnecessarily and now take it according to the leaflet, will the protection be preserved?

Good morning, I take Vibin birth control pills. Unfortunately, in the last 4 cycles about 3/4 hour after taking over the tablet, there was a one-time loose stool after which I took an additional tablet (it turned out to be unnecessary because it is not diarrhea). So for 4 cycles I took an extra tablet. In this cycle I took two additional contraceptive pills (in 1 week I took an additional one due to diarrhea and now in the 3rd week I would also take an additional one because I'm not sure if I took it (the first time it happened to me and I panicked)) I will be protected? If I do not take any additional tablet in the next cycle, the effectiveness will be reduced or can I take 21 tablets normally? Has the body become accustomed to this extra dose? I already know that an additional tablet must be taken in case of severe diarrhea and not a disposable loose stool.
