Why Is My Bitcoin Transaction Pending for Days?

I recently made a Bitcoin transaction, but it’s been pending for days now, and I’m starting to get a bit worried. I’ve done transactions before, and they usually go through pretty quickly. This time, however, it’s taking way longer than usual.

I’ve been using Bitcoin for a while and never really had any issues. I once used a similar service for a transaction, and it went through within minutes. This time, though, it’s been over 72 hours, and it’s still not confirmed.

Has anyone else experienced this? What could be causing the delay, and is there anything I can do to speed up the process?

I used Replace By Fee (RBF) to cancel an unconfirmed Bitcoin transaction. By resending the same transaction with a higher fee, I effectively replaced the previous unconfirmed transaction and increased its chances of being processed quickly.
