7 weeks!

I'm 7 weeks. I am really achey. My shoulder and neck and arms kill me. I get cramps here and there and I only get nauseous here and there.. more when I'm in the passenger of the car for extended periods..I'm pretty tired and in bed by 8 most nights but I wake up in the middle of the night and can't sleep..I also wake up in the middle of the night bc I roll over on my boobs and they kill. Other than that I feel ok. How is everyone else feeling at 7 weeks?
