Does anyone else...

Just feel like the biggest wimp ever right now? I'm 27w 1d and I have so many aches and pains (that I didn't have with my first child)! I get this pain across my stomach everyday with lots of pressure and really hard feeling. I thought it was the way she's pushing out until I was asked by someone if it was contractions... Now, the more I think about it... The more I think it could be Braxton Hicks or maybe small contractions. It takes my breath at onset and doesn't go away when I move. My back hurts constantly. I get pains in bed when I try to go from one side to the other. I can't sleep. Even just sitting in a chair or riding in the car is uncomfortable and causes pain. And she is SOOOO low all the time. I swear I feel her punch my crutch area. Anyone else feeling miserable so early on?
