Isn't it too early?

I'm 8 weeks, 3 days. Last night while I was getting ready for bed, I noticed my right boob felt cold. I looked down and my shirt was wet. Isn't it way too early for that to happen? It happened to me a couple times last week too but I kept blowing it off and assuming I got water on my shirt.  (Even though the water had been off for at least ten minutes) Anyone else had this happen this early? I don't know what to think!
