I have only been on Endovan for almost 2 weeks and I did have a much less heavy period and there was little to no clotting. My fibroids were very small to begin with so I am hoping in a few months when I have a sonogram again they are gone! No side effects. I received my order very quickly and the company always responds to my emails and questions right away. I would have given 5 stars but too soon to see if fibroids go away or shrink.
