It depends: We can not guess about your discharge without an exam.Vaginal discharge will change throughout the menstrual cycle and can be a normal aspect of the hormonal changes. 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.
