Is it normal to induce before due date?

Hi mummies, I’m currently at 38 weeks, today at checkup my Gynae told me to do more exercise and pump my breast in order to get some contractions ongoing.. and also if there is no sign of labor in next 7 days, I’ll be induced… but I thought I still have some time.. is it normal to rush into delivery mode this early (or maybe not early at all)? Baby’s estimated weight is at 3.1kg now Thanks!
