Discharge Oder

It's started a few months ago. But it wasn't as serious. I thought it would go away. It's like a milk / asiago cheese smell. I have no burning. No itchiness. No bumps. It's white when it drys up a cream color. When it first started it was a blood smell. I looked it up and it said It might be a yeast infection. I'm scared to tell my mom because I'm sexually active.. So I bought AZO yeast plus. It has controlled it. Not much discharge as before.. Doesn't smell as bad as before. But it still has a lil bad Oder.
