Induction advice?? Early Membrane sweep*

I’m scheduled to be induced at 38 weeks exactly due to my history of preeclampsia and having two 36 weekers in prior pregnancies. So my doctor offered to do a membrane sweep at 37+2 which is 5 days before we would be induced. And is next week. Is that going to be effective? We are hoping it will throw me into labor or at least dilate me enough to where I only need a little pitocin to kick off the labor. Does anyone have any experience like this? Or useful information on if it will even work?
