Sorry, I don't really understand what happened. You need to take the pills exactly how the directions read. I just switched pills. I had been taking one kind for the past 9 mos. Then, the days overlapped with the new pills so I had to wait until sun to start the new ones. And now i'm basically starting all over, I have to use a backup method for a month until these new pills are fully in my system.
Don't start pills from an old pack, if you don't finish them throw them away. If i'm understanding you, I would say you're not protected. You need to start fresh and use a backup method for a month. Unless you started the pack you're on now from the beginning, then use a backup method until your finished this pack.
