nope, not tall at all and uterus is normal. it's honestly just because i'm so skinny. my uterus has to get pretty big to actually push out enough to be seen. i'm normally really petite but i also started this pregnancy after having back to back stomach illnesses & another first trimester (m/c) so my weight was already below my normal point. i guess it's been enough time since my last pregnancy, 5+ years, so my stomach muscles had healed.
I always heard the opposite: if you're petite and skinny you'll show faster! That's definitely how it's been for me (5', 110lb). :) However, I also have pituitary dwarfism which has made my torso abnormally short, so I have almost no space for my uterus. As a result it's positioned very high and far forward even when it's empty, so as soon as I'm pregnant it's getting big. ;) I always get absolutely HUGE with my pregnancies, and this one appears to be no exception!
