I have one period approximately every two months and they're very very heavy and what I want to know is how much blood is too much blood and can I do anything to lighten the flow maybe drink more water? Or take a certain vitamin? I'm asking because one super plus tampon does not do me good but for about 5 minutes I have put two sometimes three tampons Inn at one time only to be right back in the restroom having to change them in 30 minutes or so I have a lot of very very large blood clots also and I want to know if this is normal this amount of bleeding and clotting.
