Hit by a train...

I'm 12 weeks 5 days, and I could almost swear I'm not pregnant and I just got hit by a 2 ton train. My whole body hurts; sometimes it aches but most of the time it's just flat out painful and it's mostly at night. I can never get comfortable, and sleep has been evading me for so long I can't remember what a good night's rest feels like. Anyone else feel like they're constantly getting hit by a train at this point?! Insights please!
