TTC after tummy tuck

I had a tummy tuck two years ago. My husband n I have decided to have a child together. Our first n only together. We are ok with it. If I need a revision on my tummy later down the road then we will do it but mainly more concerned of getting a healthy baby here. I have several friends that had a baby after tummy tuck vaginally n their stomach went totally back flat after birth. However, I have had two c section and I really want to had a vbac. I have heard that you can and I have heard that you can't. Does anyone know?
