Symptom Spotting, Tww, a special kind of hell

Ladies. I stay up at night researching early pregnancy symptoms, because I'm currently 12 DPO feeling crampy one my left side, exhausted, got the runs (sorry...🤫), nauseous, my eyes are burning, got a nose like a bloodhound all of a sudden, and to top it off got a weird pain behind my ear/side of my neck.

So is this all in my head cuz when you want a thing soooooo bad your body manifests these symptoms or is it the real deal?

I hate feeling like a psycho. Gonna wait a few days more I think. It's so hard to wait! AF due on New Years.
