Breast leaking milk could this be a pregnancy sign?

Hey ladies,
​I've all ready got a little girl she's 13 months. And we are TTC for our second. Due AF 16 this month. Did a test few days agai because I've got symptoms, but I've noticed something else weird. I stopped breast feeding 8 months ago and since TTC and possibly being pregnant I've noticed my breasts are leaking a bit of milk again. Could this be an additional sign of being pregnant?
