These are questions I had when I got it. Chlamydia can mimic signs of a yeast infection. I had a yeast infection took the meds and it wasn't helping turns out I had chlamydia. It can cause vaginal odor. It took about two week before it started I had a lot of discharge and it was yellowish. When you take the meds it takes two-three days for the symptoms to start clearing up. Everyone's body is different so your body reacts different. But these were questions I googled and nothing like this popped up when I searched on here.
