abnormal bleeding between periods, on birth control.

I gave birth to my daughter in April of 2011. Since June of 2011, I have been on the birth control pill called Avri.
For 3 months he had me on Apri, and I was experiencing bleeding throughout the package, and at the expected date of menstruation.
He then switched me to Avri, which I went back to him with the same issues after 3 months, he said for me to just wait a little longer.
I've now been on it for 9 months and still no change. I'm taking my pill at the same time every day, and I haven't missed a pill in over 2 months. Last months cycle was 'normal' I started spotting mid week before the expected menstruation week, and so I thought maybe I was okay. And now, this month I've been bleeding since day 10 of the pill pack, and at one point it was as heavy as a normal period. I have two pills left until the start of period week, which will come with a normal period, for a total of 3 weeks bleeding.
The bleeding I'm experiencing isn't heavy enough for use of a pad or tampon, but its dark red almost as if I'm actually bleeding, with brown clots. I have slight cramping and I'm exhausted.
Going to see my doctor Monday, but I'm looking for somebody elses opinion because this cannot be normal, and I'm extremely fed up.
