VBAC vs C-SECTION

Anyone trying to decide between a VBAC and c-section? I had my first vaginally. 17 hour labor got stuck at 7cm and needed pintocin to finish up. Second baby was breech, therefore required a c section. I have a scheduled c section for Feb 12th but doubt I will make it that far for several reasons. The plan I have with my dr is that if I do go into labor on my own before Feb 12th I will try a VBAC. If not then I will have to do the c section because I cant have any pitocin. The closer it gets the more indecisive I am. I have Big babies and this one is likely the biggest so I fear I will labor for a long time and end up getting a c section anyways. Please share your story/decision. Thank you
