If your fee is high enough it will be confirmed in around 10 minutes... So all depends on money, miners will swarm and fight to grab your transaction if fee is high
How do I get my bitcoin back (or confirmed) though?
Your transaction has two confirmations now. Yesterday the network's number of unconfirmed transactions dramatically increased, and the fees needed for fast confirmations increased at the same time. The number of unconfirmed transactions has gone back down now and your fee is OK for the current number. This website can usually recommend the best fee to pay.

However, the network is experiencing sudden surges in unconfirmed transactions. If you want to be certain of getting fast confirmations it might be best to pay slightly more in fees than that website recommends. If you do that your fee should cover any sudden surges in unconfirmed transactions.
