7 dpo nausea but negative test? Help!

Hey guys I'm so anxious for this baby it's unreal. I took a test this morning because I could no longer take it. I'm only 7 dpo. But then again, I got 4 positive days of ovulation test so now I'm worried. I've been feeling nauseated and flushed in the face. And I distract myself because I feel like I'm thinking things. But everytime I eat a bite of food I feel disgusted. What should I do?!
