Baby just wouldn’t stop screaming! help me please!

Whilst I’ve managed to calm him down for a moment I need your guys help. So, woke up this morning to my baby fidgeting and shouting (he does this everytime he wants his bottle) so made him one and got ready to give it to him. When it had warmed up I started feeding him like i always do, nothing different. He was fine until he got 2oz in then he started pulling away. So that’s my cue to give him a burp. So he had two burps and i tried again, he was still spitting it out. So I changed his nappy and tried again, still spitting it out. So I changed his clothes and burped him some more the whole time he was screaming crying (he never ever cries, mainly because I get whatever he needs before he gets to crying point but also he just usually shouts and makes noises to get our attention) but this was like a choking on air, blood curdling kind of scream. I started crying and decided he really doesn’t want that milk and it was really upsetting me that he was so so unhappy. So i’ve put him with me in bed in his favourite cuddle position with his pacifier and he seems somewhat okay for the minute. However he’s only had 2oz since his last feed 4 hours ago and normally he’s having 6/7oz! So i’m really worried and confused i just don’t know what’s going on?!!
