5 weeks & 4 days

Okay, according to my LMP from my doctors office I am 5wks&4days. I haven't experienced any morning sickness yet. I got queasy one time and that was the thursday before the 11/17 when I found out I was pregnant. I have cramps that come and go, not in my belly but on the below my stomach and above my vaginal area. I went to the ER and they said it was implantation and I was fine. I feel pregnant because my boobs are really sore. But am I supposed to feel like there's a human being inside of me? I am a first time mom. & I was wondering if any of you ladies have experienced this also.
