Is it normal to smell period blood before your period?
Mostly.Normal for most people
A mild metallic or musky smell around the time your period is due can be normal, even before you see bleeding. A strong fishy or foul odor, especially with itching, pain, or unusual discharge, is worth getting checked.
Your sense of smell may pick up normal vaginal discharge or a small amount of blood before your period starts. Blood can smell a little metallic, and vaginal odor can shift during your cycle—bodies aren’t exactly fragrance-free.
If the smell is mild and you otherwise feel fine, it’s usually not a concern. If it’s strong or fishy, or comes with itching, pain, or unusual discharge, check in with a healthcare professional.
