Ooooh... I guess thats whats the problem then.. I've tried sweeping my private keys into my electrum wallet but, once again, I don't know if it's gonna work, as the transaction shows as 'unconfirmed'..?
It has worked.
By sweeping your private keys, you actually made a transaction to your electrum wallet.
Now, your transaction has been broadcast to the network and you should be able to see that on block explorers as well. It will be confirmed sooner or later.
The confirmation time depends on the fee rate you used for your transaction. Whatever fee you paid, it shouldn't take long. Network isn't busy.
