Nausea while weaning ?

GPickles

The past few weeks I've been weaning from pumping at work.  I still nurse when I'm home, but am down to only pumping 5 minutes on my lunch break.  The past few days I've had crazy nausea, abdominal pain, headaches, & hot flashes. No I'm not pg, I've taken more than one test already.

Jut wondering if this is coming from cutting down from pumping & if others have experienced this as well, or if it's totally unrelated to BFing.
