I don't know if I'm having Braxton hicks. I'm 34+2. Sometimes I cramp but they aren't painful and if I sit up the cramping stops. (I'm usually at my desk looking at a computer and lean forward to do so.) I feel like he sits pretty low, maybe that's why there is cramping? My back hurts but that's nothing new. I'm a FTM and don't know what to expect.
