Not tissues, -- a piece of cotton ball, a little more than half, can be compacted and placed into your nostril, even if you are only worried about the nose bleed occuring.
Try first so that you don't have a big sideways bulge deal on your nose -- that's too much cotton, and it will feel uncomfortable anyway. The right amount of cotton will feel ok after a minute or two, and you can leave it in place while you are onstage. And sing, even.
If bleeding starts, it shouldn't get past the cotton ball, but just in case, keep tissues handy in case you get a gusher.
