Is it normal to smell blood before your period?
Depends.It depends
A faint metallic smell around the time your period is due can happen, especially if there’s a little spotting. A strong fishy or foul odor isn’t typical and is worth getting checked.
A metallic, iron-like smell can come from a small amount of blood or spotting before your period, even if you haven’t noticed bleeding yet. It’s also possible to notice your usual vaginal scent more around that time; bodies are not exactly subtle about their schedules.
If the smell is strong, fishy, or foul—or comes with unusual discharge, itching, pain, or burning—check in with a healthcare professional, since those can point to an infection or another issue.
