I know I know... some people don't feel anything until even later, but I had to ask for those who have had similar experiences...
Pretty sure I missed the flutter stage altogether and started feeling little mini thumps or kicks, like baby finger pokes, around 17 weeks, something a bit stronger and definite at 18 weeks, and since then nothing.. no flutter, no kicking, and I'm almost 20 weeks now.
Meah. I'm not freaking out, just a little anxious about it. I thought once I started to feel actually kick movement it would become increasingly more regular. I feel great otherwise, but it was nice having the reassurance that baby girl was in there and moving around.
