Can coming off the pill affect my period?

I made a mistake and didn't realise that I was almost finished with my pills, so now I've run out. I was on my period when coming off them and on the last day that was my last day on. Then I find out I'm still on, and then I'm not. I'm bleeding on and off now and I'm not sure whether I'm coming or going with it at the moment!😅 could this be a result of my hormones and the pills?
