9 dpo symptoms...too early?

I have very visible veins all over my chest (I've never experienced this before), I get several dizzy spells throughout the day where I feel kind of spacey, some nausea, acid reflux (very uncommon for me), and I'm so tired Lately if I don't nap I feel like I'll pass out. Is it normal to have this many symptoms this early? Could I have ovulated early? I don't track with opks because this is my first month trying and it was a last minute decision. Any advice or help would be super appreciated!
