What Are The Side Effects Of Taking Lutera?

I just started taking birth control again after taking it for 7 years then stopping for a year. I stopped because it was causing melasma on my face. Being sexually active, I decided going back on the pill was the best idea but I was still concerned about melasma. My doctor suggested I go on Ortho Tricyclen Lo. Unfortunately, my insurance didn't cover it, so she put me on a generic low dose called Lutera. I was a sunday starter, and was expecting the pill to shorten my period this cycle. It has done the complete opposite. I am now on day 12 of my period. I know that these things take time and my body needs to adjust, but seriously, I went on the pill in the first place because I was having 8 day long periods!! Is this normal? I have been reading a bunch of birth control forums and there are a lot of women complaining about lutera.
