Is my baby getting sick? Only 11 days old.

My baby scares me. He was fine i was bf him & then i started patting his back so he could burp & then milk came out of his nose & mouth. ! km 21 years old & im a ftm. I got so scared cuz baby started crying loud & seemed like he couldnt breathe! Hes alot better now. But i do notice his breathing being really short & fast ! My babys only 11 days old & idk what to do . Hes currently sleeping but keeps making litttle noses everytime i move him or when he takes a big breayh. Couls he be in pain? Normally he sleeps in his crib but 2night he'll sleep w me just oncase he throws up he wont choke & all be able to hear him .
