Nausea but still too early?

I’ve been feeling nauseous after I eat but sometimes just comes out of nowhere. Hubby and I got busy day after end of period. Week later I’m feeling nauseous but supposedly shouldn’t be because ovulation should barely be starting. I decided to take a test and it was negative. I’m supposed to start in 10 days. Dont know if I tested too early or I’m just giving my hopes up. Anyone have anything happen similar?
