So confused again!

Erika
I'm currently 18 days late and had 2 negative HPTs. I didn't ovulate until CD18 then 4 days later I started spotting; that went on for 4 days. Now I nauseated everyday all day until eat something, and at night I'm extremely thirsty. My dr finally ordered some lab work today; my fingers are crossed. I hope I'm nauseated for all the right reasons.
