noriday 28 mini pill

Hi I'm on the noriday 28 day pill atm....been on a few others but reacted badly with my migraines and irregular periods when I'm not on birth control also my partner and I aren't ready or thinking about kids yet.....anyway been on it for about 4 months, first month was fine got my period all good normal for me on birth control but the next month I missed....wasn't pregnant took tests and didn't notice any changes. The next month I got my period again.....now I'm due for it this month and I'm wondering if my cycle will be 2 months instead of one? Could this be my new normal?
