Baby Burps?

I was sitting watching TV last night with Tasha on my stomach, purring, when I felt what I can only describe as burps and bubbles coming from the left side of my stomach. It could be a) protests from having dinner at Taco Bell (yes, I know better) b) echoes of Tasha's purring, or c) the baby moving! I'd like to think it was c), and Specken and Tasha were talking to each other. Haven't really felt them since, so we'll see. Had some strange dreams last night, so everything could have been the effect of a). Three more weeks till the 20 week ultrasound!! I really don't know how people can wait till the baby is born to till out the gender. I can hardly wait three more weeks, much less 5 more months!
