Irregular period after stopping bc

Hey everyone. So here is my story. I was on the pill (Aviane) for a year and a half. This past December I stopped taking it because my husband and I want to start a family. After I stopped it I got my period a week later..no biggie. Then I went 4 weeks without my period which is normal for me. I was supposed to start my period January 29th but started a day early on the 28th..again no biggie. Here's the problem..I was supposed to be done yesterday but last night my period started again heavier then ever! Is this normal 2 months after stopping bc? I'm going on 8 days of this period :(
