FTM fussy baby won’t eat

FTM the past couple days my baby is extra fussy. He slept great last night but it’s just getting worse throughout the day. He isn’t eating much, but acts like he wants to eat. But as soon as we try to feed him he just spits milk everywhere. And he cries every time we try to lay him down, even when holding him. He will only fall asleep sitting up. I can call my doctor tomorrow. Just didn’t know if anyone had any ideas. I feel so bad for the little guy!

Edit: he’s two weeks old if that makes a difference. And formula fed.
