Deal with my husband

So I'm only 6 weeks along but I made a bet with my husband. He thinks I'll go overdue but I think I'll go early. I went a week overdue with my son but I know extra physical work can make you have your baby early. Now I obviously don't want to have it too early but I'm trying to go I little early. I will be taking care of a 1 and a half year-old and will be doing a big move. Do you guys think I'll win?
