Nausea few days after ovulating?!?!

I have PCOS and irregular before BC. I took birth control and stopped after 6 months. I last ovulated 2 weeks ago and 3 days later started experiencing nausea. I have had nausea every day since then and notice a loss of appetite. When I do finally eat, I'm super picky and that's unusual. I am not sure what to think of this because it's been 5 long years of TCC #2. Supposed to start today and nothing yet. Scared to even take a test and get my hopes up. Has anyone else experienced any symptoms like this after ovulating?
