Are you protected greatly still on placebo week?

Danni • I love him
I just switched pills this month and I only ever used the one with 28 active pills. The new one I'm switching to is orysthia. It has a placebo week which I'm not used to. Am o still protected that week? And do I need a back when I switch pills? Some say not some say just 7 days since I already have hormones in my body.
