MEMBRANE SWEEP?

currently 38wks4days and i have ten more days till my due date but i feel like i have ten years i had my cervix checked two days ago i’m 1cm dilated and 90% effaced also the midwife felt his head head almost as soon as she stuck her finger inside they are going to perform a sweeping of the membranes at 39wks2days to hopefully induce labor, for the past week i have had super sore hips i barely sleep cause i’m constantly having to turn sides, extra mucus and watery discharge, more colostrum leaking from my nipples, and i have pelvic pressure/pain what is the likely hood of the sweep working 24-48hrs afterwards?
