Implantation?

Br

Hi ladies. I have a quick question. Hubby and I have been ttc for a little over a year. Im regular in my cycle, have been for years, haven't had early AF come until today.... my period isn't supposed to come for another week. Could implantation be a red color or is it always a pink/brown color? Really hoping this isn't my period coming early. Its only there when I wipe, and only happened once so far today... TIA!!
