Hi everyone! I think I'm going into labor?

Hi everyone! I think I'm going into labor? because I didn't remember the exact date from my period due to an irregular cycle (I was breastfeeding), and by calculations from my due date it's any day now? My son was born at 39 weeks 4 days, now I'm already 39 weeks 2 days, and there are no signs at all, not even Braxton Hicks. Did anyone's labor start on their due date? They usually say second births and girls are born earlier. It seems like the opposite for me )
