baby hasn't moved up?

Alana • Married | TTC #3 w/ APS | Mommy to 1 girl 👧🏼 & 1 boy 👦🏼 & 3 angels 👼🏼 |
Same spot low on pubic bone (like four inches below belly button) at 19 weeks. How can I move her up?
Lady using the Doppler last week mentioned that they're usually at the belly button but that my baby just likes it low. But she scared me :(
