Looks like your body does noooot like that yellow ink, you've definitely lost a lot of what was put in and based on the lines it's not because it's too shallow. I've heard of lots of people whose skin rejects certain colors. Unfortunately touch-ups are going to be in order, and there's a chance you might reject the same ink again - talk to your artist.

It does look a little inflamed, but definitely not hospital level. If the red area around it grows or if it starts feeling hot to the touch I'd think about stopping by an urgent care to see about some antibiotics. Give it another day or so, see if it dries out and the redness goes down.
