Labor with no contraction pain....help

Nikita
With my 2nd child I had no pain I could not feel my contractions and my water did not break until I was at the hospital. The only reason I went to the hospital was because I started spotting and when I got there I was already 6cm and in active labor.... I never had pain or signs that I'm aware of and now I'm scared to death I'm not going to know I'm in labor with this baby either. We now live 30min from the closest hospital and i do not want to have a baby at home.... has anyone else had this and know of any other signs I could watch for?
