to change or not to change

      
I am currently on the pill called Feanolla and the first month was good until the end when I started bleeding heavily. I am now on my second week of my second month and I'm still bleeding a lot. I went to see my doctor and I now have a pill called Cerelle. I don't know whether I should carry on with Feanolla or change to Cerelle? I need some help. I just want this bleeding to stop. I'm so down
