With my first one, I felt pregnant because I was so tired and sick. With this one, I only felt tired at work but I think it was work related as well. I didn't feel sick and my boobs didn't really hurt. I can completely relate. In a few weeks, though, when your pants become a little tight...you may start to feel more pregnant (or you may just start to feel big like me but each person is different).
Pretty soon, you may be writing to us saying, "I feel so pregnant - my belly is just huge!!" It will all be good and you will be basking in the pregnancy glow!! Also, feeling the baby move is by far the best part of pregnancy. If you don't feel pregnant until that time, it is definitely worth the wait!!
