So.. BFN at 8 dpo.. Still hope?

I took a test today because today would be my "6 days before my period" and I got a BFN. I've been having some odd symptoms like breast soreness, pinching cramp like symptoms in my abdomen and increased appetite, which I normally don't get when I PMS. I tend to bloat the day of AF. Question would be... is there still a possibility that I can get a BFP, maybe after the expected day of AF? (I'm a TTC newbie btw 😄)

Thanks girls!
