Panic attack or possible pregnancy?

Bl
Last night I had a tough time falling asleep. Every time I would doze off I felt as if puke was coming up so then I'd sit up and my heart racing 1000mph. I was shaking horribly too, and had multiple hot flashes. It was uncomfortable sleeping on my boobs because they felt sore. Now it's morning; I feel better, boobs are still a little sore but not as much. Only strange thing is my stomach is sore as if I've done 100+ sit-ups yesterday and I'm recovering from it. I'm 9dpo.
