Reply to Period double time?!

I am going through this. 6 weeks pp started taking Nora Be mini pill and continued with nursing and never got a period, insurance changed brands to Jolivette back in September and as soon as I started that brand I was having periods nearly every ten days. It was insane. Went on like that for three months until I just finally stopped taking it altogether. Still waiting to return to normal cycles. I am still nursing my 13 month old as well.
