Green was born in Cardiff, growing up in the Llanedeyrn area of the city. She is one of four children born to her parents, Dave and Cathy Sellwood. She has three brothers. She played football as a teenager but gave up playing on a regular basis at the age of 16, working several different jobs. Green worked at branches of Tesco and Morrisons, in a call centre and studied plumbing in college.
Green decided to return to playing senior football in 2012, joining Cardiff City. She joined Yeovil Town in 2016 and spent time on loan with Italian team Chieti Calcio Femminile during her time there, making five appearances for the Serie B side. In 2018, Green joined FA WSL 1 club Brighton & Hove Albion upon the expiration of her contract with Yeovil. Green had previously continued working full-time alongside her playing career prior to joining Brighton.
On 18 October 2020, Green was seen to be awarded 2 yellow cards in a 2–2 away draw at Everton by referee Lucy Oliver but was not sent off. Toffees boss Willie Kirk told BBC Sport, "It's frustrating the referee made that mistake."
Green made her debut for the Wales women's national football team in 2012 against Norway. Green was named in Wales' squad at the Cyprus Women's Cup as a centre-forward. Wales manager Jayne Ludlow moved Green from her usual position as a defender to play as a centre-forward for a match against Finland, in which she scored.
