If you have a vaginal discharge you probably have a vaginal infection, particularlly if there is an odor. A yeast infection causes a white thick discharge and may cause itching. Hemophilus vaginitis can cause a greyish discharge with a "fishy" odor. Trichomoniasis is a STD that causes itching and burning. If you have a discharge, see your doctor it is not normal. Do not douche before you see the doctor, he will need to check the discharge to see what is causing it. If you douche too much this can cause a discharge. You actually never have to douche, douching can rinse away the normal vaginal fluids and the body will secrte more to replace them creating a vicious cycle, so stop douching.
