What are the signs of labor?

I am 34 weeks pregnant. Wondering what are signs of labor coming? Could I possibly have him soon? I’m lactating a cloudy/yellowish fluid. Today, I found that I have lost about 3 pounds. I have not lost my mucus plug that I know of. And my water has not broken. No contractions, besides Braxton hicks (non-painful). Just some cramping. And my cervix is dilated at what I guess would be a one or two. Any advice or information to help settle my mind.
