Does Polaring also protect against pregnancy during a 7-day break?

Good morning. I put my first polaring puck on February 4, then took it out on February 25th , the withdrawal bleeding came on February 28th. On March 3, I co-wrote and put the next puck on March 4 at a fixed time. Has protection been maintained? Should I be afraid of pregnancy if the puck also protects during the 7 days break and I joined the 6th day and the next evening at a fixed time I put a new puck
