Get tested for BV infection. Get tested for BV infection. We all get them at some point or another. The awful smell sounds like BV. Bacterial vaginosis.
If you drink energy drinks or take vitamins, these excess nutrients may cause more vibrant blood. I too have experienced the Neon Orange Blood symptoms. Any vitamins that are Flavins, ie Ribofavin, turn yellow. Flavin is the Latin Flavus, meaning to turn yellow. Energy drinks have high levels of Riboflavin, which even though you can't "OD" on Riboflavin, it has to show up somewhere. Like in urine, it becomes more yellow and in blood, well, Yellow plus Red = Orange. Since I began drinking energy drinks, my cycles have consistently been bright orange-red. I drink 1 about 3 times a week.
Unless there's a conspiracy, I believe the Mass Orange Menstrual Blood onset happened shortly after the introduction of Red Bull, AMP (My Fav), Monster, Full Throttle, Nos, etc. Women are beginning to have orange periods en masse. Probably from a huge quantity of Riboflavin in their bloodstreams from energy drinks.
