Implantation bleeding or just an early period?

Okay ladies, my fiancé and I have been trying for over 6 months. Well today I went to the bathroom and had an usual color of “blood” but I had none when I wiped. I went to the gym with a tampon in and had a little on that so I assumed I’m starting early. I woke up the next morning and there wasn’t the usual amount of blood on my tampon as if I would be starting. The funny thing is, it’s 8 days early and I’m pretty regular! All the days line up with implantation bleeding but I know it’s pretty rare. Can anyone give me any insight on this?
