I've had white vaginal discharge for a few months now. there's no odor that i can smell/no itch. could this be a yeast infection or something else?

It depends: Vaginal discharge will change throughout the menstrual cycle and can be a normal sign of the hormonal changes of pregnancy. On the other hand, vaginal odor can be a sign of bacterial vaginosis. Vaginal itching can be a sign of a yeast infection. Sometimes vaginal discharge can be a sign of a sexual transmitted infection. It is a good idea to get checked out.
