When you change your tampon or go to the bathroom during your cycle days, you may also notice changes in the color of your blood, but maybe this time you notice something else unpleasant: the smell.

"Menstrual blood contains blood and tissue from the lining of the uterus, so smells can change from cycle to cycle," says gynecologist Alyssa Dweck. But when menstrual blood smells metallic or fishy, ??does it indicate anything about your health?

Why does period blood smell metallic?

Some women have described menstrual blood as having a metallic smell, and this is due to the high iron content in the blood, say gynecologists. It is normal for the vagina to smell and no, it should not smell like perfume or a bouquet of flowers. Many women smell more acidic during periods and this is directly related to the pH of the vagina.

Why does period blood smell fishy?

Some odors are definitely more disturbing than others. "A fishy odor during periods can be a sign of a bacterial infection," explains Dr. Dweck. This is caused by an imbalance of bacteria in the vaginal biome. Disruptors that can affect are antibiotics, hormonal changes or exposure to multiple sexual partners.

Other reasons for the smell of period blood

According to the Mayo Clinic, abnormal vaginal odors can be a sign of a forgotten tampon. Keeping tampons in for more than eight hours can increase the risk of developing toxic shock syndrome (a bacterial infection that is mainly caused by tampons that are placed in the vagina).

When should you see a doctor?

If the smell of menstrual blood bothers you, it is best to schedule a visit with the doctor. In the case of bacterial vaginosis, antibiotics are given. However, it also happens that period odor problems do not need any treatment.
