Implantation or period? Heartbroken..

Abby
I was due for af around the 8th of the month, but I just went to the rest room to find some bright red spotting. Is it to late for it to be imp? Just curious also does glow change your ovulation days when your period comes early? I'm so at a lose as to why my period when come so early and why I'm not pregnant yet. :( im heart broken..
