Signs of early labor?

Ok so I'm currently pregnant with baby number 2, I'm 34 weeks at the moment. I was wondering if anyone could tell me what the warning signs for labor are? Not like "oh I'm in labor right now" but like you were gonna go into labor soon I guess? With my first I was induced, but with this one I feel like I might go into labor soon. Idk why it just a feeling i have. Could he have maybe dropped? I honestly am not sure what that feels like either. I'm really just curious because I don't want to go into labor early.
