The past few days I noticed a fleck of something in my right nipple. I thought it was just lint or a speck of something so I removed it and went on my day. The next day it returned. I removed it once again and inspected it, only to realise it was definitely a dried liquid. I pressed on my breast/nipple and a large drop of a thin, dark brown liquid came out. I am not pregnant nor have I ever been although about three weeks ago I took an emergency contraceptive. Is there reason to worry about this? I have never had anything like this. Will be making an appointment with my doctor but wanted to see if anyone here has had a similar experience. Thank you!
