Apri As A Birth Control And Starting A New Pack

Patient: My girlfriend has been taking apri for birth control for 10 years, and when she started, her doctor recommmended her to start a new pack of pills when her period started each month, thereby missing most of the 7 days of sugar pills. By her own decision, she recently decided to start taking all the 7 days of sugar pills then starting a new pill pack. Is this ok for her health, and will this still work as effectively as birth control? Thanks.
