Lactation after early miscarriage?

Fay

So it's been 6 months since I have breastfed and I haven't produced any milk. Today I turned and brushed up against the wall and starting leaking a combination of yellow colostrum, clear and thick white milk from both breasts. I had an early miscarriage 2 weeks ago at 4 weeks and 2 days. I'm not sure what to think of this. Has anyone had anything similar?
