Too early for pregnancy symptoms???

I'm 8dpo my breasts are sore, I've been dizzy, had bad headaches, slight cramping, using the bathroom more, I've had ALOT of cm very wet all the time ( never had this before), and super tired all the time. My bbt is up but that's to be expected right after ovulation. Is it too early for pregnancy symptoms or is it just AF on her way? I'm trying not to read to much into signs just curious.
