Aviane and anemia

I just started my 3rd pack of Aviane. One of the reasons I started taking birth control was to lighten up my period due to anemia. Well, so far its only made my periods worse. The first pack i had breakthrough bleeding for almost 2 weeks. It was heavy, the cramps were worse, felt sick, and worse depression/anxiety. I went to the doctor and he said this was "normal" and that I should continue the pill. During the second pack I bled for over a week and it was heavier, bad cramps and a headache for a week. Not to mention my "period" never came during the placebo pills but I know it can take time to regulate. I just started my 3rd pack of pill and I'm not feeling well. Just nauseous, sick and depressed again. Just last week when I was on the placebo pill I felt just fine and now i've started Aviane again and i feel horrible. All I know is that if bleed irregular/heavy this month again, i'm either going to go off this horrible stuff or go to the doctor to find a new birth control that doesn't make me feel sick and depressed all the time!
