Hi Lizzie. I thinnk it really depends on your start weight and the time of the month. For me, I lost 8lb in my first week but it had been totm. Then week 2, when most people have a low week, I had another 6lbs but then again I do have 10 stone to lose to be at a healthy bmi.
When I did LL, I lost 13lb in my first week and 5 in my second week and I only needed to lose 6 stone that time!!!
You're scales may only say 2 at the moment but wait til tomorrow as it could dramatically increase.
Good luck for your weigh in x x
