So how early is too early to take a test?

Brooke
I'm super impatient and my period is due in 10 ish days. I'm having all the symptoms. Nausea, heartburn, sore boobs, hungry all the time, food aversions, and fatigue. My hubby says it's too early to be able to tell, but I've done this twice now. I know my body. I'm just impatient.
