When my PCOS was discovered I chose the Mirena Birth control. It worked great. I understand everyones different but it totally regulated my period. It went from restarting everytime I had intercourse to only occuring once a month if that with light spotting if I had intercourse. I was on it for about a year and a half and had it removed when we decided to TTC. I was pregnant 3 months later and my periods from the time it was removed until the time of conception were normal.
I hope things get better for you... If you consider at anytime to restart birth control for a little while, I am a satisfied user of Mirena and plan to have it replaced after the birth of my son...
I hope your angel finds it's way to you soon...
