Why Does My Tampon Smell Funky?

Sometimes, a tampon might carry an unpleasant odor when removed—and while a mild, metallic scent from menstrual blood is normal, a strong, foul, or fishy smell is worth paying attention to. According to Dr. Mary Jane Minkin, a clinical professor of obstetrics and gynecology, if your tampon has a pungent, rotting odor—what she describes as “really strong and horrible like something died”—there’s a good chance you’ve left a tampon in longer than you realized.

Forgetting a tampon happens more often than people admit. When one is left in too long, especially past the recommended 4 to 8 hours, it can become a breeding ground for bacteria. This not only causes a rancid smell but also increases the risk of toxic shock syndrome (TSS), a rare but serious condition. If the odor is persistent and accompanied by itching, discharge, or discomfort, it could also signal bacterial vaginosis (BV)—a common imbalance of vaginal bacteria that often produces a fishy odor, especially after menstruation.

It’s important to trust your instincts. Your body typically doesn’t smell “bad” when it’s healthy. A slight change is normal during your cycle, but anything overpowering or unfamiliar warrants a closer look—literally. If you suspect a lost tampon, try to remove it gently. If you can’t, or if symptoms persist, see a healthcare provider promptly.

Staying mindful of timing, using the lowest absorbency needed, and alternating with pads can help prevent issues. And if in doubt? Don’t brush it off. A funky smell isn’t just uncomfortable—it’s your body’s way of asking for attention.
