Discharge

I’m having yellow discharge, and I don’t know if that’s normal. I know there are lots of different kinds of discharge, but no one has ever really taught me about them (which is a little embarrassing as I’m an adult now).

My boyfriend is coming back here in 36 days, and I want to be healthy down there for myself and for him, you know? So if the yellow discharge isn’t normal, how do I fix it? Just by drinking water and eating healthy? Or do I need to do something else too?
