2 weeks PP feeling off

Kaity • Wife • Momma • GSD Wrangler
I'm 2 weeks PP and for the last 3 days I've been really dizzy, lightheaded and queasy. Not nauseous enough to not eat or vomit, just like a motion sickness? It started as soon as I decided not to breastfeed anymore and am letting my milk dry up. I can't really stand for more than 10 minutes without my vision going blurry. And I don't even trust myself to walk around with the baby because I stumble sometimes. I'm calling the doctor in the AM but wondering if anyone else has experienced it? I'm totally fine if I'm sitting or laying down...
