Anyone feel like baby is low?

Laine
I'm 14 w 2 d, and when I use my Doppler at home I still feel like I have to put it pretty low to get the heartbeat. Does anyone else feel like baby is lower than normal still? It's probably a little above my public hair line and I thought by now the uterus had moved up further in the abdomen. This is my third baby so you'd think I knew better but I don't remember this before!
