implantation or impending doom of AF

Kortney • Hopeful soon to be mommy
So I have had cramps all day today not bad like AF cramps but constant over the middle of my stomach. I had light pink and creamy cm today but not enough to get on my underwear. I am 5 days from AF and on cd 10. I have been nauseous and hot all day. What ya guys think is it AF coming or is it implantation?!
