I only breastfed for 2 weeks and still occasionally get a tiny leak- I think it just takes a really long time to fully go away!
I breastfed for 2 weeks at the very start and still leak even though my baby girl is 5 months old now! Think it can just take ages to dry up 😂
I'm no expert but I imagine its milk. Aslong as your breast aren't hot or firm or any lumps I wouldnt be worried. May be that hormones are still sorting themselves out?
