A pending transaction can be nerve-wracking when you are watching your funds sit in limbo, but in most cases it is a normal part of how blockchains work.
When you send a transaction, it does not confirm instantly. It waits in a queue to be picked up and added to the blockchain. During that window it shows as pending. Usually this lasts seconds or minutes, but it can stretch longer for two main reasons: the fee you attached was low, so the network deprioritised it, or the network is congested with many transactions competing at once.
Most pending transactions eventually confirm or, if the fee was too low, drop out and fail, returning the funds to your wallet. Either way, your money is not lost while it waits.
Patience is often the right move. Some wallets let you speed up a stuck transaction by resubmitting it with a higher fee, but a beginner is usually safe simply waiting for it to resolve on its own.
