Good Emma!
I think that women in particular can find Atkins a very up and down affair, scales-wise.
Anyone who's also been on a VLCD will recognise the overnight three to six pound 'regain' after eating extra carbs. And remember, most VLCDs are based on around 60 nc per day! Their low calorie component keeps dieters in ketosis. If I eat 60 nc a day on Atkins I regain.
When the scales go back up a bit now I just sigh and try to remind myself that, whatever I may or may not have eaten, it could not possibly have caused a regain of so much actual fat - physically impossible!
Keeping your nerve, and your head, is vital on this plan! And you've managed to keep yours.
