Can a transaction take 2 days?
I send bitcoins somewhere almost two days ago and they still haven't arrived.
Any ideas whats happening. Any way of cancelling and getting it back?

My first thought is that maybe you set too low transaction fee?
Here  (https://bitcoinfees.earn.com/) you can check the average fee and transactions time.

For it to confirm?  Yes.  It can take much longer than that if you don't include a sufficient transaction fee.


You probably used a wallet that didn't fore you to use a high enough transaction fee.


You could try importing the private key into some other wallet and creating a replacement transaction with a higher fee.

But, will that Tx with high fee propagate unless the previous one is dropped by majority nodes?

That depends on how low the original transaction fee was, and how long it has been since the original transaction was sent.

If the fee was very low, then the majority of nodes may not have every heard about it.

If the transaction was sent a long time ago, then many nodes might already have dropped it from their mempool.

Is there any tool (preferably online) to check current status of an unconfirmed Tx?

yes it can happen and take longer that that also  ;D

if the fees are too low the transaction will not be
treated as a priority instead will be pushed down the
queue so to speak.

If you sent the transaction (or received it) you should be able to determine what the transaction fee was.

You can check any block explorer website or API to see if the transaction is in a block yet.

There is no single source that can tell you about EVERYONE's mempool.  Each node maintains their own mempool.

For the past few days, YES, there was a heavy congestion in the blockchain, which made the confirmation of transactions slow. I am sure it will be resolved soon.
