Who agrees that subsequent pregnancies go in to labor earlier than the first?


I was just wondering if people have experienced going into labour before their due dates with their second or third or fourth  pregnancies and how early? I hear it everywhere, that you will prob go into labour a little earlier than (going overdue) with the first when your expecting your second because your body knows what to do now etc. Does anyone think this is true? My first child came right on he's due date my 2nd 6 days early my third 9 days early and I'm currently 36weeks 4 days so I'm just wondering if I could go into labor before expecting date.🤔
