You should be confident in yourself and your training, and not be afraid to go for it. The worst that could happen is that it don't work out, but even then, you should get some valuable experience in the process. If you learn from your failures, they can be considered successes, so don't be afraid to fail. As far as I know, it is not necessary to have a specific sports first aid qualification, but there are lots of programs that offer additional training in this area. It may help you out to seek additional training in this field to help you become more confident with yourself.
