Is it normal to smell something right before your period?
Mostly.Normal for most people
Yes, a mild change in vaginal smell before your period is common. A strong or persistent fishy or foul odor, especially with itching, pain, or unusual discharge, is worth getting checked.
A mild change in smell before your period can happen as hormones shift and discharge changes. You may also notice sweat or your usual scent more around that time; bodies aren’t exactly subtle about the menstrual cycle.
If the odor is strong, fishy, or foul and sticks around—or comes with itching, burning, pain, or unusual discharge—check in with a healthcare professional, since that can point to an infection. Avoid trying to cover it with scented products, which can irritate the area.
