Unconfirmed Transactions
They will probably be confirmed eventually. But you don't have to wait. You can just form new transactions that spend the same outputs with the normal fee. The fact that there exists a conflicting unconfirmed transaction will have no effect on other transactions that attempt to spend the same outputs. You can be 100% sure they won't both go through, since an output can only be spent once. Unfortunately, depending on what tools you have, this may be difficult to accomplish.
