Light cramps... Again!?

So i’m 5-6 dpo(i’m pretty sure is 6). I got left pelvic cramps 2-3 dpo, no big deal right? Then yesterday I got some veryyy light cramps and they went away. Today, I’m having light cramps again. Besides that, my breast have been feeling this weird tingling sensation on and off, but very light.

I’m not supposed to get my period for another 8 days and I’m veryyyyy regular. When I have my period, I usually cramp the day before and the same day, not 8 days before.
