Why is it not recommended to skip the bleeding break while taking birth control pills?

Hi I use orlifique for almost 2 years I wanted to move the month 1 time I read that it is not zalwcane or it has some effect on health, cZy deregulates the cycle (usually I have 4 tablets placebo bleeding)? Why is it not recommended, is the protection against the weight maintained? I know that this is an individual matter but is it a good smamopoczucie is often if so what you can expect?
