After winning the Icelandic championship in 2014, Guðný took a two-year hiatus after child birth. She returned to the court with Fylkir at the end of the 2015–2016 season. After the season she signed with ÍBV.[3]
On 22 March 2019, Guðný tore her achilles in a game with the national team,[4] resulting in her missing the rest of the ÍBV games in the Úrvalsdeild kvenna and the playoffs.[5] On 16 April, ÍBV terminated her contract due to her injuries.[6][7]
