i was just having a shower and noticed my aerola are getting bigger and there are little pimple like things all over my nippples and when i squeuzed them colustrum came out and i stopped breast freeding nearly four years ago so i've been dry as. is this a preg sign or something else. my main concern though is there was some dark green fluid coming out of one of my nipples sorry if tmi could this just be old milk stuck in one of the ducts or is it something more serious. sorry i'm nuerotic i know
