Cant hear the baby..

I hear my heartbeat just fine and Im 35 weeks now. But I dont hear the babys heart rate at all. And if I try adjusting it around my belly, I get sounds but the sounds are from my movements or accidentally tapping my phone. Not to mention you have to be in a really quiet space. Maybe you can hear the baby and Im just mistaking it for something else but it doesnt give me much relief use this app.
