Probably high progesterone?

So I have no idea when I ovulated. I'm only CD 17 so I would think only a few days ago. I have headaches, nausea, dizziness, mood changes, tired and feel all around strange. I know it's to early for pregnancy symptoms so possibly my progesterone levels are high this month. Never felt like this until a little closer to my period. Hopefully this is a good sign.
