-TMI WARNING- implantation bleeding?

Taylor
My period isn't due for another 2 weeks and I've never been irregular. This picture was taken over 8 hours ago and I haven't bled at all since. I usually cramp the day my period starts if not a few days before. Also, my flow has always been heavy the first 3-4 days. It's never started out this light or stayed that minimal for as long of a period as 8 hours. Could this be implantation bleeding?
