Hopeful tmi

Amanda • Married for 6 years. 2 year old miracle baby girl. Expecting baby #2 in February 2017!
So for the last day or 2 I have been cramping some and then yesterday evening my boobs started hurting bad and I never have breast tenderness. And they were really hot then I noticed a clear liquid coming from my left nipple. I know it's way too early cause my period isn't due til the 14th but I went ahead and tested and of course it was negative. It's got me wondering tho cause I was only 3-4 weeks pregnant with my daughter last time and I started lactating. Could it be? Trying not to get my hopes up.
