Help?

A

I have noticed these last 2-3 months, about a week or two before my period my discharge is a little like yellow and thicker. Also, around the opening of my vagina will be uncomfortable, kinda like itchy, but not bad enough that I itch it. It’s just a discomfort. I had a yeast infection back in January but I have gotten it treated, could it be it hasn’t gone away fully? Or is there something else that could cause this?
