You have to wait , no one know when it will be confirmed. The next time use at least 0.0001 btc as fee, if you want to put zero as fee use greenAddress.it (but also the other part should use it).
Yes , I do use , I made this one just for test. Anyway , greenAddress.it is cool , thank you for your information!
