Colostrum at 26 weeks?!

clarissa
Hello,
I am pregnant with our first baby. The weirdest thing happened tonight...my boobs have been terribly itchy. Basically to the point I want to scratch and scratch and break skin. While I was doing that I noticed something wet...pushed on them a little and clear-ish liquid came out. Is it colostrum? Is it normal for it to come in this early...26 weeks? Or is this not considered early for that? Thanks in advance!
