What wallet you are using to send this transactions? If you send it via blockchain.info they will cancel it after 24 hours if remaind unconfirmed. Other wallets will keep sending it you need export your keys and open it on other wallet to send it.
Yeah I'm using blockchain.info. It's not a lot of cash but it's never nice to lose anything. I'll guess I'll just wait until tonight to see what happens. Thanks, I've moved coins around a few times without any hassle this is the first time anything like this has happened to me!
