Pregnant on the Mini Pill?

Caitlyn
I've been taking the Mini Pill for about 9 months and it slipped my mind due to wedding craziness to take 2 of the pills. I finally realized after my friend's wedding that it's been about 2 1/2 days since I took the pill last and I had sex twice. Currently I'm breastfeeding and haven't gotten my period back. What are the chances I could be pregnant? Anyone have any experiences?
