I think I may have felt movement!

Obviously being a first-time mom, I do not have a lot of experience with pregnancy ;) But I think the other night, when I was 19 weeks 6 days (yes, I know exactly how far along I am; can you tell I am so excited for Februrary?), I was laying in bed, and I just felt a tiny bit of pressure in one spot. It wasn't gas, it wasn't hunger; it was something different than I'd ever felt before. That was Tuesday, and ever since then, I've been noticing it more and more. It's usually at night when I'm laying there, but sometimes it'll be during the day, too, although I obviously notice it more when I'm just laying there, as opposed to when I'm working or walking around, etc. It makes it seem so much more real now that I can actually feel the little guy/girl moving around in there!
