S.C.
L., I am a labor and delivery nurse of 5 yrs. This is not a common thing, but it does happen. The "thin" part of your uterus is the most important, where the incision is. It can also be called a window. Basically your uterus grew back very thin where your previous incision was. The risk in this is uterine rupture (uterus breaks wide open). Depending on how thin it was, if you were pregnant again, it could take as little as 2 or 3 contractions to break that old scar open and cause a uterine rupture. This can be life threatening for mom and baby. I would take your Dr's advice very seriously. I also have to add that Ellen's advice in the previous message scares me. She is wrong in sooo many ways. A VBAC is not an option for you. And YES, moms and babies die from uterine rupture. That is why it is such a big deal....
