Feeling kicks really low?

I'm 19w tomorrow with my first and I'm happy to report I've started feeling kicks! They aren't super regular yet and I mostly feel them when I'm reclining on the couch. When I do feel them I put my hand on my belly to try and feel from the outside. Sometimes I can, but whenever I do it seems like it's really low--like right above where my pubic hair starts. I thought my uterus was supposed to be higher by now? Is this normal?
