Implantation bleeding?

Sarah • Trying for baby #1 ✨🍼👶🏼

Hi Ladies,

Currently getting small amount of very light pink with a bit of brown spotting. I around ovulated 8th or December so today being 9 DPO I am experiencing cramps and this spotting (see image). My period isn’t due for another 5-6 days I have around about a 27-28 day cycle. Is this implantation bleeding? And how long should I wait to test?
