How do I tell if its a yeast infection of BV? I had BV a few weeks ago and my Dr. gave me meds for a week and it went away but now something has come again. It is very itchy, and the discharge is cottage cheese like, but no fishy smell. A smell yes, but actually kind of....sweet? I don't know...I'm not sexually active nor have ever been and I am on birth control, prescription antacid, and an antidepressant.
