I am a similar weight too you and havr the same problem. I found that I have been in a size 16 since I was about 14stone and am now 12stone 6. Been smaller than this and STILL been in a size 16. My goal is to get to 11.7stone because surely by then, I will be a size smaller.
Like the others have said, it will come off, you're not that far off
