I don't see any reason why you couldn't have a successful VBAC. You are not doomed to a C-section at this point. Contact your local ICAN chapter: http://www.ican-online.org/united-states-chapters/#id and find some VBAC friendly doctors and midwives.
FACTS:
OBs are trained to be surgeons. They are not as comfortable with natural birth.
A tilted uterus is no reason for a C-section. In fact, usually a tilted uterus resolves with a pregnancy. Unless your OB did a terrible job in your C-section, it is not tilted anymore!
When your mother had her first C-section, it was likely a vertical cut and not a bikini cut as usually used today. Keep in mind that your incision that matters is the interior one that you can't see...not the scar that you can. In those days, it was considered safer to have multiple C-sections. We know better todays that it is not safer for most women.
When you really learn about birth, you will learn that the size of your pelvis does not matter. What will matter is that you go into labor on your own. Please take a good birthing course, like hypnobirthing or Bradley - not a hospital course that teaches you to shut up and take your epidural and wear the monitor like a good little patient.
The measurements are completely inaccurate when you get to be 35+ weeks. The science is there to prove it but doctors like to use their machines so they do - then they scare you with bad information!
Please feel free to contact me if you have questions. I was suckered into a C-section with my first - Doctor insisted big baby and overdue. I am certain he was NOT overdue and he was not 10 lbs only 5lbs 8 oz. My second baby chose his own birthday and was 8 lbs 8 oz.
Cheers,
