Leaking nips.. Already?!

Meg
I'm currently 30+5 and my nips have been leaking, usually right after getting out of the shower. It's been a long time since I've been pregnant(my son is 8) but I don't remember them leaking this early. It started about 3 weeks ago but was clear fluid, now it looks like colostrum. Is this normal? I don't go back to baby doctor until next week so just curious if anyone else is experiencing the same thing?
