Amniotic Fluid spit up

So my baby was born two days ago. Every time we lay her on her back she gets gaggy, to the point where it sounds like she’s choking and when I pick her up to hit on her back to get whatever up at first it was amniotic fluid so I figured it would be gone after 24 hours after birth. Well now she’s doing it with my colostrum that’s she’s eating. I can’t even sleep without holding her propped up because as soon as she’s on her back in her bassinet she chokes and spits up. Ugh I’m so hoping this goes away.
