Of the respondents to the survey, 72% said the issue they experienced remained unresolved a year after giving birth.
Chief executive of the online community, Justine Roberts, said the trauma had"long-lasting effects", adding:"It's clear that women are being failed at every stage of the maternity care process - with too little information provided beforehand, a lack of compassion from staff during birth, and substandard postnatal care for mothers' physical and mental health."
She added:"A maternity system that puts women at the heart of care is not some kind of unfeasibly high goal - it is the bare minimum that women have the right to expect."Responding to the findings, a Department of Health and Social Care spokesperson said the government was"committed to making the NHS the safest place in the world to give birth" and improving support for women before, during and after pregnancy was a"priority" in its women's health strategy.
