what is this?

Talia • Pregnant with baby #2!
My poor 3 month old baby woke up with what looks like a rash on the side of her face/forehead/over her eye and her eye was runny (clear) 
She felt really warm so I stripped her down until I felt like she was cooled off and then just put a onsie on her
I know she isn't feeling well because my girl ALWAYS wants to be held.. Usually cries when I put her down. And now she just wants to lay on the cold leather couch. 
She was fine yesterday 😭😭 any ideas?
She still feels warm
I've been putting a cold wash cloth on her head and gave her some infant tylonel
