Yes! Yes! That is my most favorite site...it is endless!!! So much info, and I've been doing some heavy research in the past week! It is the best I've found, too!
Here's a site with a very informative video on endometriosis. If you have dial up Internet, such as I, allow a few minutes for it to completely download. And...be sure to have the volume on.
