*tmi* Almost fifteen weeks pregnant, lactating?

🌟🌛Tabi🌜🌟
This is my first pregnancy, and I've noticed my nipples start to itch, so if I pinch them (scratching hurts) I start to leak clearish stuff with a white tinge from my nipples. The more I squeeze the more it comes out. Happens to both of them, is this the pre-milk stuff I've read about? Isn't it like way early for that?
