If the child was a stillbirth it wouldn't be registered on the BMD index.
If the child was born elsewhere it will be registered where they were born, eg another county/country as many single women were sent away from home to unmarried mothers homes to give birth
Potentially she was registered/given another name other than she was known by/used.
Spelling of her name or an error in transcribing in the index could be different.
Have you looked for a baptism record?
