Implantation bleeding 5dpo?

Brooke

Hi there I'm wondering if 5 and 6 dpo is too early to have implantation? I've had cramps and very light spotting since 5dpo I'm now 6dpo and still spotting here and there throughout the day. It's not even enough to get onto my panties... Only when I wiped. I have a few girls telling me it's impossible to implant at 5dpo I'd love your input. I typically do have break through bleeding starting around 8dpo before my period...but never this early.
