Movement?

The first time I *think* I felt movement was in Oregon on a family trip we took on July 7-14 2012.  We went to Cliff and Mary's (Grandpa Dobson's Brother) beach house/condo in Newport Oregon.  The development that the condo is in has an indoor, heated pool and hot tub.  Everyone (Grandma, Grandpa, Colby, Alyssa, Lincoln, Tessa, Chloe, Jenna, Zoey, Zaylor, Ryan, Jake and I) decided to finally give in to the  kids begging to go swimming.  I was 15 weeks at this point.  Getting into the water just felt different being pregnant. Its very hard to describe. It felt like there was a bubble in my abdomen that I was suddenly very much aware of.  It was an odd sensation. Jake was laughing at me because almost the entire time in the pool I just stood in the deep end by the edge with my hands on my belly.  To me it felt like a bubble, but feeling it with my hands felt like a little rock in my stomach/abdomen.  Brook described it in a good way I think. Its like rubbing your tongue on the inside of your cheek.  You can't really feel it on the inside but you know its rolling around in there from it pushing other things out of the way. I'm still not positive that was movement, but really, what else could it be? :)
