How many days exceed edd before induce

For KKH, when baby exceed edd, how many days will gynae give for us to try natural labor before getting induced ? Im coming to 39 weeks still not a single sign and have a feeling ill end up getting induced as i heard most mummies exceed edd for first child 🥵 Is it possible that one day we feel nothing then suddenly next day we see early labor sign. Or usually labor sign will go on for few days #FTM
