Don't worry, six days isn't a plateau.
You've lost a huge amount of weight so far and you're body is probably just trying to adapt to such a big weight loss in such a short time. And once we get past the first few weeks, weight often comes off in chunks, with no loss for a while, then a big drop on the scale.
The secret is patience and staying 100% on plan! It's hard to say when you'll see the scale move because we're all different, but I wouldn't think about calling it a plateau unless you're completely on plan for three or four weeks and nothing changes.
In the meantime, measure success in ways other than the scale. Take your measurements, try on pants that were too small, take photos, and set some fitness related goals. There will be plenty of time in your journey with nothing happening on the scale but amazing things will still be happening inside your body!
Keep up the good work -- you're doing great!
