Stomach pains

I woke up about an hour ago, I'm getting a really bad pain, almost like I'm hungry, but 10 times worse. 
It's all across my stomach, and when I touched my stomach it's super tight. 
I'm only 11 weeks and 4 days and a FTM. 
The pain is so bad it's making me nauseous, and when I tried eating, the pain didn't subside and I had to stop myself from throwing up.
Occasional shortness of breath, not sure if that's just me freaking out or if it's the pain.
Anyone have any idea what this is, should I be worried?
