Help -> Debug Window -> Console and enter:


it should return a long code. If it does you can use the code with decoderawtransaction to see your transaction and use it with sendrawtransaction to rebroadcast the transaction.

i got a long code as return however i would prefer to cancel the transaction and not try to rebroadcast it



If core does return an error (e.g. No information available about transaction (code -5)) the best course of action might be to remove the TX from the wallet.
