The former nurse endured the two tragedies and 14 miscarriages before giving birth to a healthy daughter in 2012. But she secretly pocketed nearly £17,000 of benefits in the names of two of her dead children.
She used her son Kia, who died a fortnight after being born in 2009, and stillborn baby Shannon to claim the cash.
Lincoln Crown Court heard pocketed more than £16,000 worth of housing benefit, council tax benefit and income support.
Pridmore, from Holbeach, Lincolnshire said she was a lone-parent with dependent children in order to claim the benefits. But she failed to notify the authorities that she had moved or was actually living with her then-partner.
The court heard the drug addict was also a serial fraudster who also stole more than £30,000 from four women. Pridmore suffered her first miscarriage aged just 19 and went on to experience the trauma of a further 13 miscarriages and a stillbirth.
She was jailed for three years on Friday after admitting seven charges of benefit fraud between 2001 and 2013.
