Milk a year after breastfeeding

So I stopped breastfeeding my daughter in May 2017 (she was a year and a half and during the first 5 months I breastfed exclusively) and now after a year, when I press my nipples, milk still comes out 😮 I don't squeeze too hard and haven't tried expressing, so I don't know exactly but I'm guessing it's not too much... I was just wondering, for other breastfeeding mothers, when did your milk stop? Thank you!
