Baby too high ????

Alexis
I'm 32 weeks and lately my baby has been up so high in my ribs and stays there for so long it hurts my lungs and ribs feel so sore then I start to get heartburn really bad and my brother lost his son at 5months because he was up too high and it caused the baby's sac to bust and so the baby couldn't  breath so I'm starting to worry? Is it normal for me to be in so much pain and for her to be up so high for so long ???
