What wallet are you using?

If using electrum, you can pump the fee. Just click on the unconfirmed transaction, then you can click on the pump fee to increase the transaction fee. The transaction is taking too long because of low fee.

You may not be able to do it for free.

Or

If  the present balance on your wallet has the same UTXO, and you want to send bitcoin to another recipient, then just send using higher fee, the parent/formal transaction and the child/new transaction will be confirmed at ones which will be fast with higher fee. This is known as cpfp.
