My first period in THREE years due to PCOS.

I have PCOS and have not had a period in three years. Once I decided to go back on birth control, I finally got a period. I had to be admitted to the ER because the pain was pretty rough and the bleeding had been quite excessive as well. 
Does anyone else here have PCOS? How does it effect your life? Do you have any good pointers?
