I was playing soccer in gym cl and I rammed my toe...?

into another girls foot as we were both going for the ball. I didn't go to the nurse or anything and I kept playing. It kinda hurts to walk, but I can. This was 11:00 this morning and it's 6:30. It's not like unbearably painful or anything. Just a little swollen and ****. There was no blood and gore and stuff. I don't think it's broken. I would probably know, right? Any input?
