Ultrasound scans do not reliably establish a due date. Even when done in the first trimester, when they are most accurate, the date they give is plus or minus five days (or a 10-day window). For this reason, it is not recommended that the estimated due date be changed unless there is at least a 2-week discrepancy between the clinically-based due date and the date estimated by the sonogram. I hope by this time you have gone into labor on your own, but if not, it's your body and your baby. You have the right to informed refusal.

If you agree to be induced, I suggest that you refuse rupture of membranes until you are established in progressive labor--if you agree to it at all. Breaking the bag of waters is often done as part of the induction procedure, but it commits you to delivery one way or the other. If membranes are intact and the induction doesn't take, you can stop it and go home and try again another day.

Also, refuse to be induced with Cytotec (also known as "misoprostol" or "miso"). Its only FDA approved purpose is to treat ulcers, however, it is commonly used in the United States to induce labor. If offers no advantages compared with prostaglandin E2 (which is FDA approved) for the same purpose other than that it is much cheaper, and it tends to work faster--neither of which are benefits for you or your baby. Here is what the FDA has to say about it:

"Cytotec can induce or augment uterine contractions. Vaginal administration of Cytotec, outside of its approved indication, has been used as a cervical ripening agent, for the induction of labor . . . . A major adverse effect of the obstetrical use of Cytotec is hyperstimulation of the uterus which may progress to uterine tetany [uterus contracts and doesn't let go] with marked impairment of uteroplacental blood flow, uterine rupture (requiring surgical repair, hysterectomy, and/or salpingo-oophorectomy), or amniotic fluid embolism [maternal and infant mortality rate is very high from this]. Pelvic pain, retained placenta, severe genital bleeding, shock, fetal bradycardia [profound slowing of the baby's heart], and fetal and maternal death have been reported.

"There may be an increased risk of uterine tachysystole [contractions coming too fast], uterine rupture, meconium passage, meconium staining of amniotic fluid, and Cesarean delivery due to uterine hyperstimulation with the use of higher doses of Cytotec; including the manufactured 100 mcg tablet. The risk of uterine rupture increases with advancing gestational ages and with prior uterine surgery, including Cesarean delivery. Grand multiparity [usually defined as more than four births] also appears to be a risk factor for uterine rupture.

"The effect of Cytotec on the later growth, development, and functional maturation of the child when Cytotec is used for cervical ripening or induction of labor have not been established. Information on Cytotec’s effect on the need for forceps delivery or other intervention is unknown."
