If the baby is breech or head down, where would I feel movement?

My son was breech all through my pregnancy, i am pretty sure I felt most of the movement lower in my tummy. Now I am 39w4d pregnant (second baby) and i can feel her really low in my tummy, kinda on my side also and yesterday she had hiccups that shook my belly when usually her hiccups don't. At night her body becomes more prominent and her body just seemed different. Like on my upper left side i felt what i thought was her back and the roundness to my right didnt feel as hard as her bum has been feeling, when i pushed on it her body didnt move... if i pushed on her back then that moved... i am hoping for a VBAC so sooo nervous she changed positions :-/
