Can someone explain this to me?I read it in the Diane 35 leaflet.?

If you miss 2 pills or are just starting the pill. You need a backup method such as condoms b/c the pill is no longer working to its full or is not working yet. After taking 7 more days worth of pills, you are probably fine. However, if you do not have 7 days worth of pills left before you period starts, b/c the pills during your period are fake pills, you need to skip the period week pills all together and start a new pack of pills so you can get 7 days of active pills in to prevent pregnancy and get u back on track.
