Inactive pills.

So i haven't been on birth control that long (a month today) and when i first started my doctor told me to start on the first day of my period, start in the green area on the correct day and continue and follow the arrows. My period didn't stop when i finished the inactive pills and started the active ones. Now my period has rolled around again and it didn't come when i started the inactive pills, it didn't start until about half way through, plus i'm not sure that my period will stop when i finish the inactive pills. Is that normal? Am i taking it correctly? Am i still protected from pregnancy? 
No rude or nasty comments please!
