9dpo , implantation dip?

Kim

Could this be an implantation dip? I am 9dpo and had a .04 dip this morning (normally on my charts i show a 4/5dpo fall back rise and didn’t this month ) was crampy 6/7/8 dpo) I have NEVER seen a temp dip 9dpo and my LP is usually 13/14 days so I am still 5 days out from my period?
