5 dpo cramping?

Kayla
Yesterday I was at 5dpo and for about 5-10 minutes I had cramping that felt like I was being pinched fairly hard in my lower right abdomen. 
​I have never cramped like that and now on 6 dpo I have a dull ache where the cramps were.
Is there a possibility it could have  been implantation cramps so early?
