Help.. Implantation?

Okay so i ovulated about 5 days ago and the day before, of and after my boyfriend and i had unprotected sex and the day of and after he came inside me. Since yesterday ive been cramping but theyre not painful at all. Very bearable so ik they're not ovulation cramps. I dont get my period until feb 7th (9 days) could i be feeling implantation cramps?
