hey, i just have a few symptoms im concerned about, im 22years old and have one child, first concern is i had been on the depo injection for 3years i stopped and last injection was in october last year (2012) it is now june (2013) and i havent been on any other contraceptive and i still havent had a period, but i have had white discharge since i havent been on it aswell. Second concern is my breast have been very tender and sore (i have taken pregnancy tests and all come back negative). on my areola i have got a pimple like lump its red and white discharge keeps coming out of it aswell. For about 2-3weeks my breasts had swollen up a cup size and were full and heavier but have now gone back down. Any answer to my concerns please?? Thanks.
