Still have Breast Milk

We

I was a milk machine, I could pump 8oz out of each boob. I stopped nursing my son at 11 months he is now 2 years old but I still can squeeze milk. Is that normal? Can I completely dry it out? And if so how? I got blood work done yesterday and the hormone that helps produce milk is high and it’s not letting me ovulate as my body still thinks I’m breastfeeding which I stopped long ago. If anyone had this happened please help
