Aimee Willett, 26, from Sittingbourne, Kent, had her first routine smear test when she turned 25 - the age at which NHS screening currently starts.
Doctors gave her the devastating news in June that cancerous cells in her cervix had spread to other parts of her body and that surgeons were unable to operate.
Aimee, who lives with her fiance Michael and children Charlie, eight, and three-year-old Kaleb, has had surgery, chemotherapy and radiotherapy.
But she has now been told she's unlikely to survive until 2016.
Aimee said her case highlighted the need for a reduction in the national smear test age.
She said: "I am bitter about it and I would like to see the age lowered. I think 25 is too old - especially if a girl has had a child at a young age.
"The biggest thing for me now is for people to be more aware. If you experience anything that's not normal, go to your doctor and get it checked out and when you get a letter asking you to go for a smear test make an appointment straight away and keep it.
"I always thought it would never happen to me because I was young, but cancer doesn't pick an age group."
Aimee has now made a bucket list of all the things she wants to do before she dies.
Top of the list is to marry her fiance Michael Bond, also 26, and next is to give her sons the best Christmas ever.
She said: "We're taking the kids to Lapland UK as a surprise and we plan to spend Christmas Day at home, just the four of us, with the kids playing with their toys.
"Getting married might be a bit difficult due to money. Other things on my list include seeing the Eiffel Tower light show and Disneyland Paris with the boys.
"I'd also like to take part in Race for Life so they can see me do it whether it's walking, crawling or being carried across the line."
The Advisory Committee on Cervical Cancer Screening advised the NHS Cervical Screening Programme to raise the starting age for cervical screening from 20 to 25 in 2003.
The Department of Health said: "Evidence we have showed screening women under the age of 25 can do more harm than good which is why lowering the age is not something that's being considered.
"Other more appropriate methods are instead advised, such as getting the HPV vaccine and trying to get better diagnosis from the medical profession when there are certain types of symptoms shown that may be linked to cervical cancer."
A JustGiving page has been set up to raise money for Aimee and her family to fulfil her bucket list.
