Anybody else carrying "Baby" low

Lady • Wife&Mother
I'm 16 weeks and went to the doctor for my regular checkup and the doctor couldn't find the heartbeat, on the outside I was smiling but my heart fell thru my chest as I started thinking the worst, so she said let's check again a little farther down near my pelvis bone and bam a little faint "Heartbeat" We found it..and i couldn't have been more excited!! But has anybody else dealt with this "Baby being low"
