Mandy was found dead in a wood near her home in Worthing, West Sussex on April 7.
She was last seen alive five days before she was found on April 7.
A coroner ruled her death a suicide after suffering from “personal issues,” according to The Sun.
Her family said goodbye to Mum at the chapel at Durrington Cemetery in Worthing on June 15.
During the time of the extraordinary pregnancies, the couple Mandy and Nathan were trying to have baby number 12 because they already had 11 children.
After playing on the show, they had two more children.
Her 13th child arrived two years ago.
Mandy has previously described being the mother of so many children as “absolute chaos.”
She explained, “There are times when it can be absolute chaos; it will be dogs running everywhere, children chasing dogs, adults chasing children chasing dogs!
“Not all of my pregnancies were planned – 12 are we paying attention – you know, each one was a welcome addition.”
“Madness is normal in this house. Would I trade it for a quiet life – no.
