Pregnancy?? Feeling ewwww....?

Okay so I posted yesterday but have more to add today.. I feel gross right now so sluggish and tired, but I have a good attitude just worn out, nipples still sore since 3 days before ovulation.. I'm now 6 dpo, dizzy and crampy for 3 days, went home yesterday slept for 5 hours woke up and went back to sleep for the night, not so hungry but craving peanut butter (ewww) and a snow cone which I like but hardly ever (have to have one) I don't get it isn't it too early for all this?
