Movement

So I'm laying in bed this morning listening to the twins having a cute conversation with each other in their bedroom and all of a sudden I feel tiny little vibrations in the middle of my c section scar. Almost felt like a cell phone on vibrate, only lasted about 5 seconds but it happened 4-5 times. I'm wondering if it was baby?!?! It didn't happen with the twins until I was about 15 weeks and I'm only 10 weeks 3 days right now. Maybe I know what it is this time because I've been thru it before and know what to look for? I'm pretty over joyed this morning :)
