Continuous birth control more effective?

RyRy
Is continuous birth control a more effective form of birth control? Right now I take 4 placebo pills at the end of every month. Due to a slight possibility of endometriosis, my doctor wants me to skip the placebos and just take the BC pills. I was wondering though if this also increases the effectiveness of the BC, reducing the chance of pregnancy even more? Or is the only benefit of this the lack of period?
