Pregnancy symptoms at 6-7 DPO??

Be

So I’m only 6 or 7 DPO and have been nauseated today, as well as feeling like I need to pee more often, having digestive issues, craving chocolate like it’s nobody’s business, and am SUPER hormonal and irritable (my poor husband)!

Has anyone else had pregnancy symptoms this early? Could they maybe be implantation symptoms?
