12 Weeks Pregnant and think I felt baby flutter

Anna-Marie
I know some people will probably say it's not possible, but I could have sworn earlier that I felt the baby flutter earlier on the bus up to my Grandmother's house... It was as if someone was gently poking/tickling the inside of my stomach, I've never truly felt pregnant beforehand until this little movement earlier. Have any of you other pregnant women felt this little flutter movement, this early on in pregnancy? And what was your reaction?
