Elissa Liebke has lost three pregnancies, but only received formal recognition for one.

She received birth certificates for her twin boys who died shortly after their premature birth, but her two male foetuses, lost at seven and 14 weeks were not eligible for formal recognition as they were termed miscarriages.

From this month, Mrs Liebke and thousands of other women who miscarry will be able to obtain an optional "recognition of loss" certificate from the NSW Registry of Births, Deaths and Marriages.

"Everyone is different, however I myself would be grateful to be given the opportunity to receive a certificate of loss for our miscarried babies," Mrs Liebke said.
