Hi Tanyelx,
No one can force you to have a caesarean against your will, and if you don’t have one, you’ll eventually go into labour, so in that regard you can of course choose to have a VBAC!
A few things are worth mentioning though:
Although the average success rate for VBAC is around 75%, yours will be lower due to your risk factors. Higher BMI and not having had a previous vaginal delivery are both factors which lower the chance of successful VBAC.
In terms of a pool birth, it will be up to your hospital. If they have waterproof wireless CTG monitors, I’d like to think they would agree.
Final point to make about VBAC - infection stops tissue healing as well, and so one “caution” about attempting VBAC is if there was infection in the womb involved around or after your c-section, because the scar might not be that strong, and the chance of uterine rupture during VBAC higher.
I would however ask why you’re so desperate for a VBAC? It’s your choice, of course! But despite what people might assume, there’s been a study that shows that having detailed birthplans that people are emotionally invested in doesn’t actually change the outcome of the delivery, but does decrease the average satisfaction with the birth afterwards. I’m not trying to be mean at all here, it’s just worth considering... you say you planned the perfect waterbirth last time, and it didn’t happen anything like that. Given that experience, is planning the perfect VBAC this time round definitely going to be the best thing for you and your mental health?
