you`ve obviously been seen by a doctor recently?
I would check the prolactine leverls in blood and check your thyroid
hormone levels and I`d take a look at your androgene levels.
Your prolactine levels might be high. Are you having headaches
or have you had stress? These can both be indications of high prolactine levels - which lead to galactatorhea ( milk from breasts) -
Just in case I wolds check the pregnancy
test in 2 weeks time, to be on the safe side.
I wouldn´t worry - this is most likely stress of some sort. But check the pregnancy test anyway.
It`s most probably hormonal
