Thrush?

I don't know if we have it or not. I was googling because my nipples are burning and I came across thrush symptoms. My nipples burn bad after feeding but during they kind of itch as baby sucks. They're looking a little raw or pinkish as well. Also, this morning baby spit out a small chunk of what looked like cottage cheese. No shooting pains though. Should I call the doctor? Do I call mine or hers?
