From past 2 months am experiencing change in my monthly cycle. Last month I got my dat 10 days before (i.e on 4th dec) this month still I didn't get date. Also I have small a little hard lump like thing in lower breast which I discovered 4days back and when I touch it it is paining and also there is no swelling or redness in that area. From the month of October when I press my Breast there is milk like substance discharge.
