Yeast infection??

My vagina has been itching really really bad lately- like a yeast infection would. And I took antibiotics like 2 weeks ago so I believe that's the cause. Yesterday I went to the bathroom and had the typical yeast infection discharge- the white, thick, nasty stuff. I used coconut oil to try to treat it without taking anymore medication than I already take for other problems. So this morning, I went to the bathroom and my discharge seemed to be more yellow, but still thick. It wasn't like a bright yellow, but I felt like there was at least a yellow tint. I took medicine for a yeast infection earlier today, and I've been using cream to help with the itching. But I was wondering if there are any possibilities to why my discharge would have been yellow-looking? 
P.S.- sorry for how long this post is, I just wanted to make sure I got everything in.
