If you have had a cesarean delivery (also called a C-section) before, you may be able to deliver your next baby vaginally. This is called vaginal birth after cesarean, or VBAC. Most women, whether they deliver vaginally or by C-section, don’t have serious problems from childbirth. If you and your doctor agree to try a VBAC, you will have what is called a “trial of labor after cesarean,” or TOLAC. This means that you plan to go into labor with the goal to deliver vaginally. But as in any labor, it is hard to know if a VBAC will work. You still may need a C-section. About 25 out of 100 women who have a trial of labor need to have a C-section. This means about 75 out of 100 women who have a TOLAC deliver vaginally.
