Is Bleeding After Taking Cerazette Pills Normal?

I started a mini pill, cerazette last month. I took the first strip of the pills and then had a 7 days break, and then started on the 2nd strip. I just realised that on the minipill I am supposed to continue to the next strip the following day without a break! I am now on the 2nd week on the 2nd strip of pills, I have been bleeding for 10 days. Is this normal? (I haven't had any bleeding on this pill before now) or have a messed up my system by having that break in between?
