birth control
"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's utter misery to me, especially when they were barely 2 days long on Loestrin."
