Implantation bleeding??

I’m 11dpo, my period should be due on the 8th. Yesterday morning I took a test which was negative, later that morning and today I’ve had a little spotting. Mostly just when I wipe and a little on a light day liner. The first time I saw it it was light pink, since has been dark brown in color. Did I test too early before implantation??? When should I try testing again?
