period on the mini pill - breastfeeding

I had my baby girl in October. I've been on the mini pill since January. Still breastfeeding and supplementing with formula. Didn't get my period until march and now it is absolutely crazy.... it's spotting here and there, and then I've been on my period for 2 weeks.... anyone else experience this?  I'm so used to normal birth control with regular schedule periods that were only 3-4 days. This 14 days is killing me. 😰
