Ok mommas with PCOS: after your first postpartum period, did you return to abnormal periods? Or were they monthly?

My last period was Dec 29 2016 and before that was Dec 26 of 2014 I breastfed (and still am) so they delayed my period but now I'm just sitting here twirling my thumbs thinking when is my next period? Am I pregnant? Wth is going on?

What's going on with you guys?
