You're not weird. Lactation tends to be triggered by a drop in female hormones, most notably progesterone and estrogen as it does during childbirth and soon after. So, it could be simply due to the fact that you stopped all hormones.

When Androcur (cyproterone acetate) causes this, it can potentially be quite serious and indicate a prolactinoma, this is why it's always good to notify doctor if something out of the ordinary occurs and NOT wait. Best to catch something early on. I don't want to alarm anyone but it's best to be cautious.
AS ALWAYS, I'm not a doctor so let the doctor know and decide for themselves if everything is fine or not.
