acne
"I've had a pretty good experience with this oral contraceptive since I started taking it about a year ago.  I originally started taking it as both a birth control method and to help manage hormonal acne that I suffered with as a result of a previous IUD that left me with a hormonal imbalance.  Since using Tri-Previfem or Tri-Estarylla (depending on what my pharmacy has at the time) my acne has become significantly better, and when something does pop up it is much easier to manage.  Also, cramping during menstruation is no longer an issue for me.  The only "negative" side effect I've noticed is that I'm left with "swollen" painful/sore breasts nearly every day."
