Bubbles? Baby B??

I think I maybe finally felt Baby B!!
I was sitting at my desk at work yesterday and I felt what I can't describe as anything else but little bubbles fairly low.  At first I thought, maybe gas? But I wasn't gassy and didn't feel like that. Then I thought its 12:30pm and I haven't had lunch yet, maybe I'm just hungry? But it was too low for hunger pains.  So then I thought maybe, just maybe it is Baby B!!  I had to call Jason to tell him.  I was getting kinda worried since I hadn't felt anything yet but feeling the bubbles made me feel much better.  I haven't felt anything since, so who knows if it was really Baby B, but it was the closest thing I've felt so far that could have been.  It was pretty cool! 
Very excited for our 20 week appointment and ultrasound today!  Looking forward to seeing Baby B again!
