More and more transactions are being stopped as more and more transactions are made and increased daily. I have encountered this and I have to wait 14 days for 1 confirm transaction.
Are you sure had waiting for 14days / 2 weeks to got a block? I don't believe about that. so far knowledge., for those who have trasactions then stuck for almost 3-4 days. that's transaction would be rejected, and directly bitcoins will be get refunded(cancel).
