I have like discharge for a while now I been going to the clinic and they gave me some pills called teva and the discharge would go and then come back and its just getting worst what you think it is ?

What color is it? Does it smell? If it's an off color and smells funny, it is possible you have Bacterial Vaginosis. This is an infection, not an STD! It is caused by you having an improper balance of good and bad bacteria in your ph balance. Typically a doctor will prescribe MetroGel for this. All you have to do is fill a thin plastic tube with the gel, insert it, and push the gel into yourself each night before bed for 4-5 nights I think. Look into it. Other than that, unless you are itching/burning it's unlikely you have a yeast infection.
