Choose the right menstrual products
Some women notice a stronger vaginal smell when they get their periods; some women smell an iron-like metallic odor, and others smell ammonia.
Some menstrual products trap odor, compounding this effect. To reduce odor:
Try wearing internal products. The moisture of maxi pads and reusable cloth pads can contribute to odor. Sitting on a wet pad can also cause an infection.
Change menstrual products frequently.
Know how sex affects vaginal odor
Some women notice a strong fishy odor immediately after sexual intercourse, which is a telltale sign of bacterial vaginosis. Others notice a less distinct smell.
Sometimes interactions between semen and vaginal fluids can cause vaginal odor. Some lubricants can also change vaginal pH and the odor that comes with it. To reduce the odor associated with vaginal intercourse:
Use a condom to prevent semen from coming into contact with vaginal fluids.
Rinse the vagina and vulva with plain water following intercourse. Do not douche.
Avoid using scented or flavored lubricants.
Consider a probiotic
Probiotics support healthy bacteria throughout the body, including in the vagina. Probiotics may help prevent some vaginal infections, especially yeast.
By controlling infections, probiotics can reduce causes of vaginal odor. Because probiotics help restore the vagina’s normal pH, they also help reduce vaginal odor.
