Could you change up your diet a little? Add in more vegetables and whole grains? I have no idea; maybe you're already eating super healthy; but I have found in the past when I've stalled out that sometimes I need to just change up my routine. It kind of seems to surprise my body into losing weight again.
Otherwise, just keep on keeping on! You have done a great job so far and should be so proud of yourself! You'll get going again eventually. I know how hard it is to not see the scale moving the way you wish it would. Don't give up, though! :)
