In the season 2018–2019 she won the crosses at Poprad, Neerpelt, Aigle, Hittnau, Lutterbach, Wachtebeke, Koksijde, Eschenbach, Antwerpen, Otegem, Maldegem, Middelkerke, Hulst, Leuven and Oostmalle.

Betsema denies the facts but she was temporarily suspended by her team awaiting the outcome of the counter-expertise.

[4] The UCI proposed the rider a retroactive sanction of six months suspension, starting from 5 April 2019, which was the day her team voluntary put her on non-active status.

Betsema also forfeits all results from Hoogerheide on, which meant the loss of her 2019 victories in Maldegem, Middelkerke, Hulst, Leuven, and Oostmalle.

Betsema accepted the sanction proposed by the UCI but she and her legal counsels are still of the opinion she was the victim of a tainted food supplement.
