I haven't read the entire thread, so maybe this was already mentioned......my cramping has lessened since using the diva cup. I have since read some articles re: the materials used in pads and tampons that are "super absorbing" meaning that they draw moisture like a sponge.....pulling more out of you which can cause more cramping and pain.
I think that not only is this healthier for our bodies but it is FAR healthier for the planet.
