I need to find a b.c. method that is affordable that I can use. I am a 1/2 pack a day smoker with skin pigmentation problems on my face that was diagnosed as melasma. I took b.c. pills since I was 14 to 32. Initially to stop my continous menstrual cycle after it started. At 32, I started having mood swings and skin changes and switched to the depo shot, which dried me up to much. So, I have never been pregnant and sjust started having my period again, so need to find a pill that would work for me without affecting the consistency of my cervical mucus and that wont darken my melasma anymore than it already is.
