I had possibly the most set in stone birth plan ever. I spent 10 years perfecting the damn thing. I was determined. So so so determined to birth my way. For many reasons.
What actually happened was my EDD came and went. 14 days over my EDD came and went. At 20 days late he finally arrived, with a birth completely the opposite of the birth I planned and hoped for.
When I finally agreed to IOL at 40+19 I despaired. I thought that I would really regret it, I beat myself up over the decision.
He was born by forceps.
He was put on me.
The world stopped. Nothing else mattered.
Birth? I stopped caring at that moment.
I have no regrets. No PND (which I thought prior to him being born I would end up with due to being so set on how I would have him at home, no intervention etc).
I can't explain it, but when you have planned something for so long, and been so dead set on how you will do it, when you have to make a decision that flies in the face of everything you wanted, then you think you will live to regret it. I have injuries from my birth which I wouldn't wish on my enemies, but I have no regrets.
Just adding my story in as I suppose it is the opposite to the theory.
