Leaking milk after years

sunny

My daughter is almost 5 and I stopped breastfeeding almost 4 years ago. I have leaked colostrum for years when I get in the shower, but recently it’s became milk.

My tubes are tied but I’m still unsure if I had a chemical pregnancy last month as I had a couple positive tests that were iffy? Should I get checked out by a dr for leaking milk? Does anyone else do this years later?
