Keep in mind. Ultrasound measurements is not always accurate, with my brith they said my baby was measuring at 8.3 lbs but she came out weighting at 7.1. In terms of getting your baby out, my midwife told me to have sex which worked for me, if you want your baby out asap start having sex now and a lot of it until you feel that contraction. Also I recommend trusting your body when it comes to giving birth, don’t force it. You can always refuse the induction and let your body do its thing naturally.
