Is it normal to smell period blood?
Yep.Totally normal
Yes. Period blood can have a mild metallic or musky smell, and it may smell stronger after sitting in a pad or tampon for a while.
A mild smell is normal: menstrual blood mixes with vaginal fluids and reacts with air, which can give it a metallic, musky scent. The smell can be more noticeable on a pad or tampon that’s been in place for a while, so changing period products regularly can help.
A strong, unpleasant or fishy odor that’s new or sticks around—especially with itching, pain, or unusual discharge—is worth getting checked. Otherwise, your period having a smell doesn’t mean you’re dirty or doing anything wrong.
