I felt *nothing* until a couple days ago, at 19w4d...and then he suddenly moved down lower for a while; my placenta is high and anterior, and he has been hanging out there most of the time (i can feel the bulge often, and it's always been high and on the right side) and I think that's what kept me from feeling a thing...but as soon as he shifted, I felt a ton of movement right away, put my hand down there absently, and got a kick hard enough to move my hand away! I thought I'd get the little internal flutters or something first, but we skipped right to feeling it from the outside.
He's mostly hanging out up top still, but a few times over the last few days he has shifted down for a while again and I have felt more kicks like that. (I feel so much better about things now, it's silly. Now I just hope I keep getting these 'visits' so I don't start worrying again...)
