The girl, who cannot be named for legal reasons, fell pregnant by her 11-year-old boyfriend and is set to be the second youngest mum in Scotland.
According to the Scottish Daily Record, the girl plans to raise the baby and is reportedly has the full support of her family.
The pregnant teenager is reportedly still attending classes at her local secondary school.
The youngest mum is Tressa Middleton, now 20, who fell pregnant aged just 11-years-old.
She gave up her child after it’s second birthday after the young mum became involved with drugs.
She later claimed that the pregnancy was a result of being raped by her brother.
Only last month, a schoolgirl became the youngest mum in Britain when she gave birth.
The young mother was just a couple of months younger than Tressa when she delivered her baby.
Tressa said about the 13-year-old’s shocking pregnancy: ‘The mum should be proud of herself for keeping the baby.’
She added: ‘I just hope she carries on at school. I didn’t and still regret it. The big difference for her is having a loving family. I had nobody.’
Following the reports of the pregnancy, authorities told the Scottish Daily Record that they were ‘totally committed’ to reducing the amount of under-age mothers.
