Women from Wales' Somali community said they have been "persecuted" and have called for changes to female genital mutilation rules.
Campaigners said FGM no longer happened in Wales, but health workers continued to accuse innocent families.
Health workers must report children they think are at risk to social services and report evidence to police.
The Welsh Government said its rules were "sensitive to culture, race and religion".
FGM is illegal in the UK and figures show there were fewer than 17 cases in under 18s recorded by Welsh health boards last year.
The cases, revealed in a BBC Freedom of Information request, were in children who had been born outside the UK and not in established British-African communities.
