Bertrup began her international curling career as the alternate player for
Elisabet Gustafson. With Gustafson, she won a gold medal at the
2000 European Curling Championships, and placed 6th at the
2002 Winter Olympics. Gustafson retired after the Olympics, and Bertrup was without a team. She wouldn't return to the international curling scene until being picked up by
Stina Viktorsson in 2010. Bertrup played third for the team, and they won a gold medal at the
2010 European Curling Championships. Viktorsson left the team in 2011, and was replaced at the fourth position by
Maria Prytz. The team's lead, Sigfridsson assumed skipping duties. They won a silver medal at the
2011 European Curling Championships, and the rink was chosen to represent Sweden at the
2012 Ford World Women's Curling Championship, where they would go on to win a silver medal. The next season, the team would win a bronze medal at the
2012 European Curling Championships and a silver medal at the
2013 World Women's Curling Championship. For the
2013-14 curling season, the team won the gold medal at the
2013 European Curling Championships, a silver medal at the
2014 Winter Olympics and a 5th place finish at the
