Implantaion? Normal?? Help!!

Ladies!! Okay so I just took a pregnancy test today at 8dpo and it was very very faint. I have been cramping today and when I went pee a little bit after taking my test I noticed a little brown/red blood. Is this normal? My period is 6 days away. Ive never had an early period before. Could this be implantation blood? Please let me know!
