Black Discharge from Breast??

Hey everyone!

So last night I had a pain in my breast. I figured that my boobs where just sore from hormone stuff so I was massaging them, then I noticed a sort of grey/black viscous liquid had come out?? I squeezed again and more came out. has anyone experienced anything similar? Should I be worried? I have a doctors appointment in a month, but should I schedule one sooner?

(for more info: I am a trans woman, Been on hrt for just over a year, estradiol 6mg and 200mg spirno)
