Did you stop being able to squeeze any milk/liquid out of your breasts?

E weaned around 15 months and he is 21 months now, so 6 months of no breastfeeding. I occasionally check to see if I'm completely dried up, but as of last night I still get some drops when I squeeze my breasts. It's more colostrum looking (yellow) liquid than milky looking, but still there. I feel like this is another one of those things that no one tells you...
