"i was on loestrin for about 3 months after a year on generic orthocyclen. initially it was a great switch because the last one made me extremely moody, but the new one had no emotional effects. the first two months we annoying because i was having breakthrough bleeding. by the 3rd month i finally had a normal cycle, but after finishing the 3rd pack i noticed a lot of my hair was falling out! apparently loestrin is a high androgen pill that can cause hair loss, and with a history of hair loss in my family i should never have been on it in the first place. please talk to you doctor about this side effect before starting; i&#039;ve lost over 20% of my hair in the last week and it may last another year."
