This is super gross, drink vinegar, like a spoon only. It makes it lighter & mine 3 days shorter:) or the easy way out, eat a pickle. It doesn't work as good though. & exercise. Good luck. Mine started the day before thanksgiving ' & I was so mad. Lmao.
The heavyness and length of your periods are regulated by hormonal levels. Flour...vinegar...warm baths....will do nothing to lessen this. If you don't want them, or want them less, I suggest you look into birth control or the depo shot.
