"i have had no problems with this bc.  it seems like every brand affects people differently.  i switched from loestrin after i started losing hair.  zarah solved the hair loss.  zarah has cleared up my acne, which is a feat by itself.  i do have horrible cramps and bloating.  my biggest complaint is my periods last  full 7 days.  that&#039;s utter misery to me, especially when they were barely 2 days long on loestrin."
