Boob question lol

Im a FTM! Just turned 24 weeks today. I noticed something dry on my nipple so i decided to squeeze my boob... "milk" it almost and to my surprise, a drop of clearish liquid came out followed by a drop of white. Is this my milk already?! I feel like its so early! I want to keep messing with it because I'm so intrigued but i know better than that. Lol
