Either you have the nose of a bloodhound, she's leaking through her clothes, or hasn't changed her pad/tampon forever. It smells but it shouldn't be that strong.
Normal blood has smell
And period does too (it has a different smell though)
And if the period smells bad, I think that girl should go see a doctor cause that's not normal
