Credit card issues? ughhh?

I just went online to pay my credit card and I noticed a charge on there that says Bishop nternational for $57.00. I had no idea what it was so I googled it and Bishop Inter national is an airport in Michigan. I've never even been to Michigan. So now I'm kinda freaked out. Do you think it means someone has my credit card info? Should I cancel it? I'm gonna call capitol one in the morning but could it be something else!??
