Cramps 7dpo

Natalie • Baby Nolan born 6/17/15 after 16 months TTC 💜
So I started getting mild period like cramping around 7dpo and still have it off and on now at 9dpo. It feels like more mild version of cramping I get right before my period. Does this sound like implantation cramping or more like early AF cramps? AF is due 1/27. 
​Thanks!
