For all of you that are wondering if you can "feel" pregnant, before you know for sure:
yes!
with my son, I couldn't get my shorts up past my thighs and I was only six weeks along. By then, I was queasy, tired, my breasts were tender and unfortunately for my husband, I was a beast (due to increased hormone levels). But, if you'd ask him, he knew I was pregnant because I started to cry when I couldn't get into those shorts. Until that day, I just thought I was pmsing...
At six weeks girls, generally, you just realized that your period is late!
I thought I was only four weeks along.
But really, it depends on the person.
I've got a friend who says she started feeling "different" one week into her pregnancy.
Some people go for quite a while without noticing any changes.
I hope this put it in perspective for you
