I only "felt" pregnant for about two weeks after I found out. Before then and after that I've felt absolutely nothing. No sickness no tiredness no cravings. I'm 36 weeks now and other than a huge bump and lots of movement I sometimes completely forget that I'm pregnant.
Just go with the flow. You are one of the lucky ones. My first pregnancy was like this. No pain, I threw up maybe twice. But this one is a DIFFERENT story. Embrace it.
