Is this implantation? Pleeeeease help

Laura • I threw my pie for you
I'm 10 DPO (it was 15 but glow changed it) and AF isnt due for a few more days. today I had pinky spotting, it was nothing like my normal period, since then it's completely stopped, the little bit of spotting came back quite a few hours later. I did do 2 tests yesterday, both were negative but then I only began spotting today. I've had cramping on my left side too as well as both sides, I've felt dizzy and a little nausea too. What do you think?
