When does milk stop flowing after weaning?

So I had to stop breastfeeding at 4 months as bubs was preferring the bottle over breastmilk (we had to mixed feed) and I barely had any milk left. It's been 2 weeks since he breastfed and I'm still able to get droplets if I squeeze them. When does this go?
