You haven't got much to lose so its going to be slow and /or stick at times. Those last few lb seem to take forever to shift. But shift they do - eventually, if you persist. Don't think going off plan will help, you'll just give yourself a hard time and an excuse to put some back on again. Plus doing extra attack is not a good idea, it only really works the once at the beginning.
I was 2 weeks with no loss at one stage, near end of the time given to end cruise and the scales just wouldn't budge. Eventually I gave up on cruise and went into conso, then to my surprise I started losing some more. So sometimes the change of pace works, also try upping the exercise if you can. Patience and a bit of faith help. Good luck
