Yes, you can safely skip the placebo tablets (white) and go directly to the active part of the blister, which will effectively delay the bleeding from discontinuation for the duration of your trip.

In this situation, contraceptive protection was maintained because you took an extra pill in good time after loose stools, which ensured possible absorption of active substances. However, minor spotting or intracyclic bleeding may occur when using the new blister, which is a completely normal response of the body to skipping withdrawal bleeding.

A single loose stool that occurred 3 hours after taking the Vibin Mini tablet does not affect its effectiveness. Taking an additional tablet was a cautious and correct course of action, especially if there were doubts about its absorption. If, apart from a single loose stool, there has been no increased diarrhoea or vomiting and the tablets have been taken regularly, the effectiveness of contraception should be maintained.
