progesterone insufficiency
"I was diagnosed with hyperplasia. I was experiencing very heavy, clotty periods for YEARS. I thought this was normal until I had a month long period. This pill is heaven sent. I have not had a period for about 8 months, have lost a tone of weight, have more energy than I have had in years and I would say the only side effect is tender breasts. I cannot guarantee this result for everyone but clearly I was no producing my own progesterone."
