Early pregnancy symptoms??

I am currently 8dpo and the last couple days I've been feeling really weird. I've been having random dizzy spells and so tired I don't have the energy to get up and put something away in the next room. I've had an increase in my sex drive which I've never had before. I tested this morning and BFN. I totally am not myself lately. I have an appointment coming up for fertility options as well. I'd like some sort of feedback on what I should do. TIA
