Nipples Leaking-20 Weeks?

I’m almost 20 weeks, and today I was sitting on my bed and my shirt felt a little wet against my arm when I moved. I looked down and saw a spot about as big as a penny that was wet right over my nipple. I went and check it out and noticed clear liquid gathering on my nipple. Is this normal this early?
