Hold on TIGHT and don't give up!!
Plateaus bite, don't they? The loss IS going to happen and it will probably be as mysterious as the plateau.
Don't forget that you're making improvements in your health even if you're not seeing it on the scale. You're giving your body better things to nourish itself with. Every part of you is getting stronger. Think back to how you felt when you first started...do you feel a change in your energy or are maybe even sleeping better? Sometimes it's the little things like that we miss. And it's so gradual that you kind of forget how crappy you felt when you started. At least I did.
For me, sometimes it can help to shake things up a bit. Maybe have a couple slightly higher calorie days....or lower. Or drink a LOT of extra green tea for a few days (can help if you retain water). And sometimes, it's just a matter of patience.
Just DON'T GIVE UP. Good stuff is already happening and it's going to continue!
