Was this implantation?

Yesterday I suddenly started cramping and the intensity increased, and I noticed some very light spotting. After a few hours the cramps pretty much went away except every once and a while I’ll get a mild one, and I’m back to regular white CM. This has never happened to me before. My period isn’t due for another 5 days. Does this sound like implantation?

Update: I’m 13 DPO and tested and it was faintly positive! 2 days until my expected period. Will have it confirmed with a blood test soon. But just thought I’d update this for anyone who sees this in the future
