Like previous posters said, you are an ideal candidate for VBAC. I think every mom who's had a CS is an ideal candidate. Even moms who have CPD (not failure to progress, but a CPD diagnosis) still have a 50% chance of having a VBAC! So it's TOTALLY worth it!
There are always a lot of emotions concerning VBAC. I find a lot of obstetricians only talk about the risks of rupture, and not the risks of having repeat surgery. To you AND baby, especially if your CS is scheduled and you don't labor before it. It really is a journey. To put out numbers (which can never seem small or low enough) the risk of rupture is less than 1%. And of those mamas who rupture, only 1 in 4 are serious and life threatening. Very low. Now, compare that to the risks of CVS (where they do amniotic fluid sampling) it has a risk of 1% miscarriage. But yet, OBs hand out CVS like candy to mamas, but say VBAC is too risky. When if you see that the risk of of CVS has a 1% death rate of the baby, and VBAC has a 1% risk of rupture, where on 25% of those are serious and COULD result in death...it really doesn't add up. There is no reason a CP should refuse VBAC to you in your situation. It's very safe.
It may be worth thinking about asking your OB "HOW do you support a VBAC mom". Not just IF she does, but what does she do to HELP a mom have a successful VBAC.
HIRE A DOULA HIRE A DOULA HIRE A DOULA! They are so so important through the pregnancy to support you emotionally through the process of dealing with your fears, giving you info, planning for the birth etc. Then during the birth, supporting you through that process, especially if you end with a cesarean, then afterward, working through the postpartum recovery which if it ends in CS could be rocky.
That little voice in you that wants to experience birth is, in my opinion, the voice all us women have that help guide us through pregnancy, motherhood. It's important to keep in touch with that, even during the birth. It may not be the 'norm' of what a typical woman in our society thinks, but it is real, and normal for a mama to have that desire.
I think you are going to do great and will birth beautifully! It's important to keep in mind that you are a birthing mama who just happened not to have had a vaginal birth with your last baby. Not really much different than a mama who did. :)
Much love to you!
