Will I get a black eye?

Ok, so I play doubles badminton for my school team and tonight during practice, I got smashed directly in my right eye by the birdie, and it hurt really bad for about 10 seconds. That happened over an hour ago, and now my eyeball is just red and the corner of my eye is a bit flashy/dotty and blurry, just a bit. There's no swelling or discoloration of the skin around my eye. I'm worried if I will get a black eye since I have an orchestra concert this week. Do you think I will develop a black eye?
