Madison said she lived in a caravan in Clacton-on-Sea in Essex while pregnant and could not get a tenancy because as she was under 18.
Tendring has the second highest teenage pregnancy rate in the East of England, but it is falling.
Projects like Youth Enquiry Service (Yes) in Holland-on-Sea have helped reduce the rate by 47.9% in 10 years.
The service visits schools to educate children and provide mental health support. Yes also delivers group activities for new mothers and fathers, along with housing and sexual health advice.
The charity helped single mum Madison, now aged 20, move into a mother and baby unit where staff advised her on budgeting and how to bring up her son.
