Please help ease my mind..

So it's almost 2am here..DD is sleeping, but I'm awake holding her and staring at her to make sure she's breathing. She got her two month shots today, so I've been watching her like a hawk, she sounded like she was either trying to poop, or breathing kind of weird so I googled what to look for after the shots (when she's asleep her breathing is fine, it's just kind of a grunting she's doing when she's awake and she hasn't pooped yet today) I'm reading through and read where people's babies have passed away after having these shots (please do not turn this into a vax/anti vax debate) so now I don't think I will ever sleep again, I feel like I'm about to have a panic attack i am so worried. Someone ease my mind please?
