Wait for a day or two. It'll either come back as failed or go through. There's a lot of network congestion in ETH since yesterday possibly coinciding with status.io ICO!
Please read this article for more details. I don't think I really resolved your issue but I hope my pointer helps you out!
thanks for the article :)
I learnt about one more major contributing factor. I believe the ETH trades are now clearing off after these two near simultaneous events i.e. status.im ICO + GDAX Flash crash!
