well im 24 weeks tomarrow and i havent begun leaking yet
i guess all women are different when it comes to this and some start earlier than others?

im 37 weeks on saturday, my boobs started leaking at 18/19 weeks. and now when i hear a baby cry, or see a baby up close they leak too.

I am 39 weeks 2 days and mine are not leaking.

I'm pregnant with my first, and I started leaking colostrum at 18 weeks! I asked my OB about it, and he pretty much said pregnancy hormones affect different women differently, and yes, they can cause some women to leak very early on! Thankfully, it hasn't gotten much worse yet (I'm 24 weeks now), but every day, I do leak a few drops and especially overnight. I wake up and my nipples are all crusty from leaking.
