I'm 12 weeks with my second baby. I got pretty sick and threw up at least once or twice a day with my first and this one I just feel tired. I had a sore uterus feeling with my son and again this one I just feel tired. I don't even have a backache unless I'm walking all day long. I don't feel pregnant and it's starting to freak me out because My uterus doesn't feel like anything out of the ordinary. Do you guys think it's just because my body already went through pregnancy and doesn't need to adjust as much? Everyone has said the second time around is easier, but I didn't expect it to be THAT easy.
