Boob question

Tabitha • My name is Tabitha I`m 25::Mama to my amazing son::Wife to my crazy husband:: Baby Number 2 due 7-18-2016 👩🏻👨🏼👦🏽❤️
I am 7 weeks pp and not bf but my left boob still leaks at least once a day?! Why and how can I make it stop? Also my nipples used to be pink and small now they are brown and huge will they go back to pink and small cuz I look weird with these huge brown nipples...this didn't happen with my first baby. I feel like NatGeo over here thank God my husband is not a boob man 😫😱😱😱
