Yes. In this case, the fee of 5 sat/byte is quite lower than the normal.
I suggested you to accelerate your transaction with one of the websites above. But it's not possible in this case (at least for free). ViaBTC won't accept transactions with a fee of 10 sat/byte or lower, and ConfirmTX only accelerates transactions for free if they don't exceed the size of 500 bytes (yours is 2220 bytes).
So like I said before, just wait for the confirmation - which is probably going to happen.
