Yeah thats definetly your baby..it usually starts with bubble/flutter like feelings :)
Yeah that sounds like it. At first its just little tickles or butterflies. Doesn't take too long for it to become more powerful thuds and pokes and rolls. Congrats :) enjoy!
It definitely could be, you should start feeling your baby for sure soon and chances are it will be a simi familiar feeling. It absolutely felt like little bubbles for me when it first started, the movement Ramps up pretty rapidly past that point so in betting in a couple weeks you will know what it means to feel him/her move :)
