Implantation?

I have had very little like pink spotting when I wipe and in my underwear for the past two days and sharp constant cramps for the past couple hours today, I am suppose to start in 2 days and 3 days ago I took an ovulation 2 ovulation tests and they both were positive. Have any of you experienced implantation, is this what it is like or am I just getting my hopes up??? Also should I take a test or should I wait a couple days? TIA 😁
