its true about the caffeine, as others have said. As for leaking/ discharge, if you breastfed, it may be milk or colostrum. I weaned my middle daughter in 1995, and still had some milk/ clear fluid I'd guess was colostrum up until I had this daughter last march (im bf now too) I was pregnant a couple times in between, but still I had milk for over 15 years with no baby feeding. My breasts have always been tender, since I started developing them.
