Am I being hopeful?

On Monday, Tuesday and Wednesday last week, I felt really nauseous basically all day. It let up a bit Thursday and Friday but was still evident. I took a test from the dollar store on saturday and a FR one on Sunday morning with both being negative. The nausea came back today with a slight feeling after lunch.

According to Glow, this is My ovulation week but I had all the ovulation signs two weeks ago. Hubby and I baby danced for the hell of it twice during the time I felt like I was ovulating. Could Glow be wrong and I ovulated closer to my period than other people? Would it be too early to test? I don't want to give myself false hope if I'm Just having a freak flu.
