Evaluation Needed: You may need to go to the ob-gyn to get evaluated.

Best to have GYN Doc: Evaluate this discharge. Itchiness, discoloration, burning, and malodorous weeping are signs of vaginosis. You should be examined and if bv, treated accordingly.

Personal hygiene : Have the area clean as much as possible. Some times sweet and fuzz from cloths trapped in belly button and vagina and creat bad smell and other issues such what you mention. If the proper hygiene did not resolved your issue definitely go and see your obgynl.
