After a few months in retirement, however, she would make a comeback to return for the club's 2018–19 season. In July 2019, she announced that she had signed with Brynäs IF, drawn in part by the presence of former Modo teammate
Erika Grahm. After one year with Brynäs, she left the club after being unable to agree on a contract and seeking a new challenge. After speculation linking both her and departing Brynäs forward
Michela Cava to a return to Modo, she would sign with Luleå ahead of the 2020–21 SDHL season.
