I think I'm feeling tiny baby flutters already! I know 12 weeks is early, but it is my third and I'm fairly certain about it. My uterus has been sitting high, often over my navel, and I actually think I might be a few days ahead of my edd (actually, according to u/s I'm 5 days ahead). But anyway, I didn't expect this so early and it's really cool. Can't wait until baby is bigger and DP can feel from the outside.
