The vagina is very sensitive to changes in your daily environment, anything that affects its pH balance, will affect the smell and consistency of discharge.
Douching is a premade cleaning mixture that comes in a plastic bottle that can be squirted high up into the vagina. This internal vaginal cleaning is not a recommended routine to keep the vagina smelling fresh and clean. The active cleaning ingredients used in most douches can upset the healthy vaginal discharge and pH balance and create a yeast or bacterial infection.
