Can I skip the 21st tablet of Microgynon and start the break earlier?

Good morning, I took a tablet of microgynon 21 around 24 o'clock, at 24.30 diarrhea occurred. I took another pill a moment after I felt better, not even 2 hours of slippage with tablets passed. In that case, am I still protected and have no reason to worry? Is it better to shorten the cycle of taking to 20 tablets, or, for example, add this 21 tablet (which I took additionally) from another blister? Thank you in advance
