Abigail,
I haven't had a chance to read everyone's replies, but get yourself to an ICAN meeting! They were instrumental in my successful VBAC! Honestly, an OB will go on and on about the risks of a VBAC, but won 't go over the risks of a repeat Cesarean...and the risks of a repeat Cesarean are way more common, there are more of them, and they can be just as bad as the dreaded uterine rupture you'll have thrown your way when you mention VBAC. Oh and BTW, uterine rupture can STILL happen with a repeat section! OBs are surgeons and some of the reasons so few attend VBACs is because: VBAC works best when left alone and they just don't know how to do that; so few see natural--and I mean natural--births anymore; they don't make as much money from a natural birth as they do a medicated, and ultimately surgical, birth. You have to find someone who knows what they are doing, and not many do anymore, which is sad. There are a few REAL reasons for Cesarean (placenta previa, accreta, cord prolapse, transverse lie) and so many reasons that really, truly are not medically necessary--doctors are too scared of getting sued, and instead of learning how to deliver breech babies for example, they are just taught to cut. So many things that "suddenly" go "wrong" in the hospital which end up in surgery are iatrogenic (http://www.iatrogenic.org/define.html), which means doctor-caused. A cascade of interventions to a perfectly healthy mom and baby suddenly causes problems and surgery is needed. The US is killing more moms and babies (at a 33% section rate) than countries that have 3% section rates--our cut happy culture is not producing better outcomes.
My second child was born three months ago, at home, and it was the best experience of my life! During my first birth, my body was no longer mine, the experience was no longer mine, and I was talked into agreeing to MAJOR ABDOMINAL SURGERY, only to find out later that the reasons were not true (I acquired all my records after the fact). When my second son was born (breech, BTW!!!), the entire experience belonged to me and my son and husband. Because he was breech (I didn't know--he turned that week!), had I been in the hospital, I either would not have been allowed a VBAC, or they would have performed unnecessary procedures on me (episiotomy, forceps delivery of the head) to "help" him out--my son came out easily and without any harm or damage to either of us!
Do your research. The REAL research. Read Henci Goer, Ina May Gaskin, "Pushed" by Jennifer Block, "Silent Knife", and so on and so forth. Go to ICAN for information and support. Learn which doctor you should switch to for your best chance at a VBAC. Find out exactly how to fight for a VBAC in a hospital. Hire a doula. Maybe even decide on a homebirth! ;-) Surrounding yourself by women who have been there, done that, will make all the difference in your best shot at a successful VBAC. You will hear over and over from women who have had successful VBACs and even VBA2Cs! You'll even hear from CBAC moms who can tell you how to make the most of your experience if your VBAC attempt ends up in a repeat section--you'll also know that it was necessary, and it can help in emotional healing.
Ultimately, the decision is yours, so if you do decide for whatever reason you don't want to try for a VBAC, do me one favor: don't schedule your repeat section. Let your body go into labor on its own. At least then you will know that baby is ready and you are decreasing some of the complications involved in scheduled sections.
Good luck! Sorry, I hadn't meant for this to be so long. I'm sure you can see this is a passion of mine! LOL
P.S. To Shelly: my C-section son was seriously coneheaded, and my breech VBAC had a perfect head! And my son was in his car seat next to me as I labored in the car getting home from work--in transition, no less--as my husband coordinated getting him picked up by my parents. Convenience and aesthetics are not good enough reasons to think a C-section is a good idea, and there are plenty of birth traumas associated with C-sections...Just sayin'. Yay for your three(!!!) VBACs!
