get a tapered stopper for next time, it's not the rubber ones, some kind of plastic but it is impossible to push it into the carboy as I almost did on my first batch.
Take whatever you can think of and sanitize it and pull out your stopper and ideally replace it with a new sanitized stopper and airlock. Not sure how close you are to a LHBS, but stoppers and airlocks are dirt cheap you should always have a spare on hand in case Murphy shows up.
I wouldn't worry too much unless you had a lot of junk or water from your unsanitized airlock fall in when you put it back in.
When you get ready to pull the other one make sure you saitize every surface you can reach around the stopper and the neck of the carboy just in case, might not hurt to take an alcohol wipe to the inside of the neck when you replace the stopper. RDWHAHB
