Hello,
Sometimes an infection can cause menstrual blood to look and smell funny. If associated with a foul
odor (remember blood itself often has a characteristic smell), tenderness or fever, this should definitely prompt a visit to the gynecologist. Commercial pad such as Always or Kotex are made from synthetic materials and plastics, these prevent aeration to your vulva so get your groin hot and sweaty, as ably as mortified this give the sound environment for germs and yeast to multiply.
