Today unconfirmed Bitcoin transactions are at 162400. It has gone down from the all-time high of 230k plus. If you find that your transaction is stuck and your wallet doesn't offer the option to increase the fee after sending it then the viabtc.com/tools/txaccelerator/ maybe of use to you. After entering in your transaction id and solving the captcha you can send an additional fee to accelerate you tx.
Good Luck!
