I can't really remember when I stopped leaking exactly, but I know it was a looong time after I stopped breastfeeding. I stopped breastfeeding after about 4 days post-partum, and I seem to remember leaking throughout my entire post-partum period 6-8 weeks afterwards. Stimulation is what made me leak. I'm pretty sure it's completely normal to still leak, although you should be close to it ending.
