Mini Pill Question

Kristen • Hubby & I have been together 10 years, married 11/8/14. Angel Baby - 10/22/15. Rainbow Baby Girl, Maggie, born 10-18-16!
I just had my 8 week postpartum checkup. I still haven't started my period, and I'm exclusively pumping (with an over-supply). My doctor prescribed me the mini pill for birth control as I was on a different pill beforehand. My question is, my period will come back with the mini pill, right? I was hoping that with breast feeding it would stay away for awhile....I'm not sure I'm ready to start that back up again by starting the pill back....What has been your experience? Thanks!
