What Causes Breast Pain And White Vaginal Discharge After Coming Off Birth Control?

i am 23 years old, have been on the pill for about 3 yrs. i just stopped last month. it has been a month since my last period, i have had breast pain since i finished my last period, and i have been having a whitish vaginal discharge? is this because i have stopped taking the pill, is it normal to have breast pain for that long, i don't think i'm pregnant and i'm hoping i'm not.
