My waters broke first and labour was 31hrs with a lot of intervention and a crash cs after a failed venture and failed manual rotation. I haemorrhaged and we both sustained injuries. I felt a lot of guilt, robbed of the moment of birth which I don't remember and ended up with PTSD.
It took me a lot of time to have a second and like you, I wanted a healing vbac. I wanted to do it "right". Thankfully, I had some birth trauma counselling and debriefing while pregnant because it became clear that I was setting myself up for failure. I'd decided an emcs was the enemy, hospitals were bad, intervention was giving in.
The obstetric consultant who did my debrief was fab. He explained that waters breaking first were often a sign of a poorly positioned baby ie the waters break because they're lying oddly not because you are labour ready. He said in my case, the long labour, uncontrollable pain, back to back contractions etc all hinted at the same thing. The lack of descent and intervention at the end was inevitable. It was all decided long before I made in-labour decisions iyswim.
It was like a lightbulb going on. I'd been so wrong. I kept telling myself that bodies know what to do, nature should have been allowed to do what it needed to do, I gave in to intervention and didn't trst my body. NO. If the human body can take over in a war zone and birth babies, then the fact mine couldn't do it with medical assistance in a first world country meant the total opposite. It couldn't do it full stop. My baby was malpositioned when labour started. I didn't do that. It was just chance and I spun a narrative of agency and failure across it.
I realised that I truly had no choice. I planned for every outcome and positively. I researched calm, positive caesareans. I discussed different options for interventions. I stopped seeing it as a good vs bad scenario and accepted that I couldn't choose the birth I wanted but I could make choices along the path I was given. I forgave myself.
At 37 weeks pregnant, my waters broke out of the blue and I knew I had another malpositioned baby. I gave it a go anyway. Water, hypnobirthing, staying mobile etc but DS didn't descend a millimetre. After 38 hours of labour, I had an emcs. But I laughed, smiled, dh watched the surgery, we had skin to skin and bf immediately. The surgery was calm and joyful. It was a really healing experience.
I can't give birth vaginally. My babies were 7lbs and 6lbs respectively and I had all the medical help the 21st century can offer. I grew and birthed them a bit differently and it wasn't a failure or second best. Truly.
You might have a vbac and put all this anxiety to bed but please go into it knowing that there are myriad physical routes to motherhood and they are not a hierarchy.
