Dizzy spells

I have fainted close to my period every month, have since I was 16. I don't usually get dizzy spells before I faint it's more like I get dizzy and wake up. I have had dizzy spells for a day or two where it's not so dizzy that I faint but it's dizzy enough to make me uncomfortable driving. my doctor said my dizziness and fainting would get worse with pregnancy and I know dizziness is a sign of pregnancy. is it too early for me to have that sign if I'm only 9 dpo? Or with my history could it be pregnancy? my nipples are also EXTREMELY sensitive, when my breasts usually just get sore not just the nipple and not this extreme. I also LOVE my coffee and decided to "drink till it's pink" and yesterday when I tried to have a cup I smelled it and got naucious. Am I just crazy?
