I am also having the same problem, however its my right breast that hurts the most, and i to finished my period last week, it lasted almost 2 weeks and i could hardly move, i doubt mines menopause thou as im only 18.
I too am experiencing a similiar problem. Including breast pain. I believe that I have started into periomenopause. Early this year, I has skipped my period for a few months, went through hot flashes, but then after 3 months it came back and I have gotten it every month. It last long 7 -10 days. And now I have a dark brown discharge (not a lot, but daily).
I do know that a sign of not ovulating in a cycle is having break through bleeding. Your hormones might be a little out of whack. Not enough progesterone in your body cause cause you to break through bleed. I had this problem too when I was younger, I was put on bcp to regulate my periods and balance my hormones. Talk to your gyn. about the discharge and possibly hormonal imbalance.
