Differences
The term is standard in medical contexts in both dialects. In everyday non-medical speech, 'miscarriage' is overwhelmingly preferred in both. No significant spelling or structural difference.
Connotations
Identical clinical connotations. Both see a strong shift towards 'miscarriage' in general discourse due to the potential for 'abortion' to be misunderstood or cause distress.
Frequency
