I've felt that feeling of it feeling like goose bumps but I really just leaked a little. It's weird but very cool experience lol
Well I have a pregnancy book an it says most women will falsely believe that its goose bumps but its actually the areola letting out oils so your nipples stay moist but I haven't read anything over leaking milk an I didnt want to just wake up an freak out one morning cause my shirts wet ya know.
I started leaking early like at 12 weeks! But it was very little. Now I leak a lot. I am 39+4
It won't come till right before baby is here or after baby is born
