I haven't had AF back yet (stopped BF about 2 months ago) and I've had loads of EWCM for about a month - most days, so I thought I'd use an OPK as I had heaps leftover and I got a positive result.  But that seems a little weird if I've had EWCM for so long.  As I was thinking maybe I was having an annovulatory cycle and would eventually get AF.
So anyway, my question is, do OPK's work properly 5 months after giving birth or would my hormones still be out of whack?  
We're not TTC at the moment either, just trying to work out my cycles really.
