Tri- Legest Fe, anyone?!?

HI! Well yesterday I went to the doctors and she put me on the generic brand Tri- Legest Fe. Im 16 and I've never been on any other birth control, this is my first time. My doc said that this birth control can improve my moderate acne and will obviously regulate my period. I tried looking online for info about it but I can't find any helpful reviews out there! Has anyone here been on it, and if so what were the pro's and con's, side effects, etc. Any help is very much appreciated! Thank you!! (:
