Either way, there is a better option! The Diva Cup!
I know - the name is hilarious. And the idea is radical to some. Its a silicon cup, very slender, that you insert during your time of menstruation. It lasts up to 12 hours, even on your heaviest days and since its made of silicon its 100% safe. Just rinse and reuse. You can even wear it overnight. I have friend that use it and love it!
Good for your health and it SAVES MONEY. Woohoo! If I ever have another cycle (just one of the blessings of children and breastfeeding!) Im definitely getting one. They are about $33-34 and your local health store may carry them!
There is also another brand called The Keeper (made from gum rubber/latex) and the Moon Cup which is silicone like the Diva Cup. Both are about $35.
