"If you're currently taking Loestrin and experiencing mood swings/depression, etc., don't think your moodiness will eventually dissipate over time.  I've always been a fairly upbeat, positive, rational person. Since taking Loestrin (I'm into my fourth pack = four months), my mood swings have continued to get worse. I cry or tear up at the most random things, for no reason at all. I am anxious and my moods are unpredictable. On a positive note, Loestrin has reduced my period to 1-2 days a month with VERY light bleeding."
