Felt kicks

So I was in gym (not the gym, gym class) and I was sitting down mixing my own when suddenly...I got muscle spasms in my uterus. I was already pretty sure what they were, but I didn't want to call it and be salty...sooooo I called my mom, Google, forums, websites, other pregnant girl I know. They all said yes. So yay!! And like a half hour ago, I felt another. But that was like I got plucked once. Fun times.
