Has anyone started randomly lactating again??

I stopped breastfeeding my daughter back in May, i checked every few weeks to see if anything came out but they dried up nicely, well randomly today I squeezed my nipple because it was bothering me, didn’t think anything of it, then noticed my shirt was a little wet. So I checked them both and I have breastmilk coming out again! And not just one drop. Has anyone else had that? After I stopped breastfeeding my first is dried up and that was that. I thought I maybe have been pregnant this month but I’ve had negative tests. I just don’t understand what my body is doing.
