Hedin began playing ice hockey in the youth department
Huddinge IK in her hometown of
Huddinge, the second most populous municipality in the
Stockholm urban area. She made her senior league debut with the women's ice hockey team of
Segeltorps IF in the Riksserien (renamed SDHL in 2016) during the 2009–10 season. Segeltorps IF claimed the Riksserien championship title in both 2010 and 2011, capping Hedin’s rookie and second seasons with Swedish Championship gold. After three seasons with Segeltorps IF, she transferred to
AIK Hockey ahead of the
2012–13 Riksserien season. With AIK IF, she won a silver medal in the
2013–14 IIHF European Women's Champions Cup. Hedin’s
college ice hockey career began when she joined the
Minnesota Duluth Bulldogs women's ice hockey program in the
Western Collegiate Hockey Association (WCHA)
conference of the
NCAA Division I ahead of the
2014–15 season. She played four seasons with the team and served as an
alternate captain during the
2017–18 season. Returning to Sweden after her collegiate career, Hedin re-joined AIK IF in the
2018–19 SDHL season. She was one of AIK’s alternate captains during the
2020–21 season, part of the leadership group headed by captain
Sabina Küller and filled out by fellow alternates
Emmy Alasalmi,
Erica Udén Johansson, and
Line Bialik Øien. In the 2022–23 season, she joined
Färjestad BK in the
Nationella Damhockeyligan (NDHL) as the team made a push to qualify for the SDHL. After the team ultimately fell short of their SDHL aspirations in 2023, Hedin returned to the SDHL for the 2023–24 season, signing with SDE HF and taking on the alternate captaincy. == International play ==
