I am SCARED of her choking....please answer?

I have a newborn that is one week old, and I am terrified of her choking for some reason. I always burp her after feeding her bottle but sometimes I will notice her spit up a little bit in her crib. Which I know this is normal. All babies do that sometimes. But one time she threw up kinda, and what if she did that when she had a pacifier in her mouth? or spit up with a pacifier in her mouth? or spit up in her sleep and her head wasn't turned to the side? would she choke and die? Can this happen? Please tell me.
