acne
"When I first went on this birth control about 2 years ago (in hopes of curing my migraines my doctor thought may be hormonal and fixing moderate acne), I went absolutely crazy.  It made me have HORRIBLE mood swings and I found myself in a terrible mood all the time for no reason (crying about stuff I never cried about, snapping at people, etc.).  I had never been that way before this pill.  My first period on this pill was ROUGH,  I was extremely depressed and emotional and just wanted to cry in bed.  The pill did seem to help with my head aches, although it never helped at all with my skin.  It made my periods way lighter and less painful, which was a perk.  My advice is to stick with this medicine for a long time and wait out the pain."
