Feeling babies

Rebecca
Hi! I'm 20 weeks with fraternal twins, boy/girl. I may have felt a little bit of movement here and there, but nothing that I think is actual baby kicks! I'm hoping to feel them move soon, I thought I would have by now! I do feel the boy who's on the right side with his head up and legs down, poke out on the right side of my stomach sometimes. It gets hard in one little spot, and I can tell its a baby! I haven't felt anything like that on the left side where the girl is with her head down and legs up. Has anyone else had similair experiences with any of that?
