Fortune joined the Baggies on loan from Nancy in January and he has already earned praise from manager Tony Mowbray for his performances.
West Brom have the option to make Fortune's loan move permanent in the summer but the Frenchman is not thinking about such matters.
Albion are currently bottom of the Premier League table and Fortune is focused solely on the scrap for top-flight survival.
"The next few months are a chance for me to do as well as I can. I am not considering what will happen at the end of my time here," he told the Express & Star.
"My only intention is to try to help West Bromwich Albion stay in the Premier League. Beyond that I have no thoughts. It is not something that I'm worrying about yet.
"I just need to show the manager what I can do if I am given a chance. I will not think about anything else."
Fortune scored two fine goals against Newcastle but he was disappointed that West Brom still lost the match 3-2.
He said: "I was happy to score my two goals against Newcastle but it was not a perfect day because we lost. The team is what matters most."
