Implantation cramps or period cramps?

Fajar

I had dull cramps from 8 dpo on and off. I am also experiencing back aches and leg pain. Today it was my 12 dpo and i had this pulling feeling in my lower abdomen from evening. Don't know if these are implantation cramps or just period cramps🥺🥺🥺🥺 can anyone help?
