Should I be worried about my foot?

Ok i was at my wrestling banquet today and i just came back from swimming. When i was coming back i ran to hit a volleyball and i felt a pain in my foot. I immediately sat down and looked at it. It turns out I stepped on a broken bobby pin. My foot hurts but my coach said the salt water would clean it so I went in the water then i went home washed it out with soap. Then i put peroxide on it and put some antibiotics on it. The pin went in almost all the way and I had a Tetnus Shot 3 years ago should i be worried.
