If it felt traumatic, that is not an overreaction

How the birth felt to you predicts trauma better than how serious it looked on paper. That is the pattern in the evidence, not the exception to it.

Women who were traumatised by a birth that reads as routine in the notes usually reach the same conclusion about themselves. Everyone else copes with worse. Something is wrong with me.

The evidence says the opposite, and it says it clearly.

The largest analysis of what is linked to post-traumatic stress after childbirth pooled 50 studies and 21,429 women across 15 countries. Here is what correlated with post-traumatic stress, in order of strength within the birth itself:

Factor during the birthCorrelation with post-traumatic stress
A negative subjective experience of the birth0.59
Operative birth (assisted vaginal or cesarean)0.48
Feeling detached or unreal during labour0.32

Read the top two lines together. How the birth felt to the woman was a stronger predictor than whether she had an operative birth. Not a smaller side factor. The largest one measured inside the birth. Support ran the other way, and mattered less than either of those two: the less support a woman had, the more likely she was to be traumatised.

That finding has since been repeated in a study of 11,302 women across 31 countries, with different health systems, different rates of intervention and different cultures. A negative birth experience was again the strongest predictor. Ongoing complications for the woman and serious complications for the baby also mattered, and feeling that you or your baby were in danger mattered independently of whether that danger was later judged real.

So when you say it was terrible and someone answers that the baby is healthy and the notes look fine, you are not being irrational and they are not reading the evidence. Your account of your own birth is the single best predictor anyone has.

To say to the next clinician who tells you it went well"I understand the outcome was good. My experience of it was not, and that is what I need help with."
"I know it looks routine in the notes. It was not routine to me."
