Early contractions / signs of labor?

Victoria • 22. Viviana’s Mama.
Currently 35w3d Sometimes I'll get random pains / cramps throughout the day, they aren't super painful but they're uncomfortable to where I have to stop what I'm doing and breathe for a few minutes. I also feel like I'm going to gush water because I feel so heavy down there. Could this be early signs of labor? What are other symptoms I could look out for?
