Can't log in to Ultimate Team

I have now not been able to log in to ultimate team for 10 hours! I can't do anything to fix it, and it all started when I was playing gauntlet and the 3rd game glitched. I won the game but it threw me to the main menu and I haven't been able to login since. Im missing out on fut champs and gauntlet objectives... PLEASE FIX IT !!! :(
