Question about the birth control patch

Amber-Rose • Twenty-Nine. Married. 👩🏼 12/01/2015 🧒🏼 08/03/2017 👧🏼 03/02/2021
This is my third month of the patch and three days into my third week I started my period, or at least I'm bleeding and it's just like one.
Does this mean it's not working? I put it on like the instructions said and haven't had any issues until now. 
I kept it on and will continue the cycle like normal but does this mean I'm going to bleed again during my off week? Is my cycle messed up and will come during the third week all the time? 
Thank you in advance!
