Currently the transactions are getting confirmed with a minimal fee of 3sats/byte based on https://coinb.in/#fees. Your transactions will get past within this day probably. But you should set the fees manually using the GUI slider for your to get past quickly with the recommended fees. As achow said in an older post, bitcoind needs to sync completely for you to check with the current fee.

You can set minimum transaction fee by configuring the mintxfee= xBTC/KB
By this way, you are instructing your client to broadcast your transaction with xBTC/ 1000 bytes. Setting the mintxfee too low would be quite dangerous.
