I keep seeing people talking about statistics for being able to vbac. I know they aren't actually helpful, but I am interested in it anyways. How is this calculated?
Here is one calculator I have seen. They ask for information like height, weight, history of vaginal delivery, ethnicity, etc. It may be fun to see the predicted success rate, but I don't think it is accurate.
I think most of the stats cited here are based on clinical research studies that look at which percentage of women attempting a VBAC were able to deliver vaginally. Some studies break them down further by looking at the reason for the primary cesarean, whether the woman was induced, how far dilated she was, etc.
There are also "VBAC success rate" calculators that factor in a bunch of different factors to determine how likely a person is to VBAC or not, but I don't know how those algorithms work.

I put my info in to see what odds it would have given me for my second pregnancy and it said I had 71.8% chance of successful VBAC. I'm surprised it was that high since I'm short, had no prior vaginal births and had a c/s for arrest of descent.
Now if I recalculate for a future birth, taking into account that I've had a successful VBAC, the calculator gives me odds of 94.4%. Interesting.

I put my info in and it said 77.8%... obviously that can't be the sole basis. My medical records are what my be putting a stop to my vba2c plans. I wouldn't go by this calculator in real life, just my opinion.
Do you put in your pregnant weight, or your not pregnant weight? That makes a big difference in my percentages.
Good question. I put it my non-pregnant weight, since it uses it to calculate BMI. The idea of having a BMI when you're pregnant seems kind of non-sensical, since you've got a whole other human being inside you, extra fluid, etc.
