Thick white clumpy discharge. Sometimes clear and watery. But has odor?

See doctor. Any new or apparently abnormal vaginal discharge needs medical evalution. The most common single cause of increased discharge is bacterial vaginosis, an overgrowth of bacteria, especially if strong odor (often fishy), sometimes most noticeable after sex. "Thick" and "clumpy" suggest yeast. STDs are also common causes of discharge. Maybe more than one problem. See doctor; diagnosis should be easy.
