Doctors explained her baby had stopped growing and had to come out.
Speaking to The Mirror, Raybould gave her the frightening news that her baby might not live.
"Doctors explained that my baby may not come out alive. I cried and begged them to push back my chemotherapy. They said if we did that my baby wouldn't have a mum."
After 17 weeks of treatment Raybould was told her tumour has shrunk to just 1.7cm and no longer showed signs of active cancer.
The news brought her to tears, knowing everything she went through was worth it.
While life for Raybould is now close to normal, she has a high chance of relapse but remains positive she will be fit and healthy to be a mother to Lacey-Mae.
"I can't say thank you enough to the hospital staff who helped me and made sure my baby survived. Lacey-Mae was so tiny but has caught up – like she knew she had to pull through. She's a fighter. Just like her mum," Raybould said.
Lacey-Mae is now 7 months old and weights 6.3kg.
A Gofundme was started to support the family and give them a much deserved holiday when the UK's Covid-19 restrictions are lifted.
