Answer: As long as you're an appropriate candidate for a vaginal birth after a cesarean, also known as a VBAC, there's a good chance you'll succeed. Of course, your chances of success are higher if the reason for your previous c-section isn't likely to be an issue this time around.That said, it's impossible to predict with any certainty who will be able to have a vaginal delivery and who will end up with a repeat c-section. Attempting a VBAC is called a trial of labor after cesarean (TOLAC). Overall, about 60 to 80 percent of women who attempt a VBAC deliver vaginally.
These steps can help for vaginal birth after a c-section if Your previous cesarean incision was a low-transverse uterine incision (which is horizontal) rather than a vertical incision in your upper uterus (known as a "classical" incision) or T-shaped, which would put you at higher risk for uterine rupture. (Note that the type of scar on your belly may not match the one on your uterus.)
Your pelvis seems large enough to allow your baby to pass through safely
You've never had any other extensive uterine surgery, such as a myomectomy to remove fibroids.
You've never had a uterine rupture.
You have no medical condition or obstetric problem (such as a placenta previa or a large fibroid) that would make a vaginal delivery risky.
There's a doctor on site who can monitor your labor and perform an emergency c-section if necessary.
