Pregnancy possibility?

Courtney
I am now 15 days late for af. I'm never late but I keep getting negative tests and I don't know what to think. I woke up very nauseous and last night I got chocolate candy with caramel inside and couldn't eat it even though it's my favorite type of candy, and couldn't drink my caramel Starbucks coffee which I usually love. I dipped Pickels in ranch(I hate Pickels) and loved it. And I can't stop drinking orange juice. What do you all think, I greatly appreciate any opinion before my appointment on Wednesday.
