Where's my period?

Any other July 2016 mamas who still haven't gotten their period yet?  I'm breastfeeding but lately my face has began to break out significantly, my milk supply has dropped some and I feel a little bloated.  Don't know if those are signs that it's on the way or not? My LO is also teething and is not taking in as much milk due to being uncomfortable (even with ibuprofen and teethers) so I don't know if these are also side effects of slowly weaning?
