Firstly I would recommend you look at setting yourself small goals, like half a stone at a time rather than thinking you need to lose 3 stone, otherwise it seems like a mountain to climb.
Secondly, I would say it's not unheard of to stay the same or put something on the second week. Did you stick to plan 100% or do you know you cheated in some way? With regards to cravings, these are normal too and you need to find some low syn treats you can eat to satisfy your appetite and there will be lots of this site if you have a search around. Also, the week of your period (or * week as it is often referred to) is the week you will often put on weight but it comes off again the following week.
I would sit and consider the reasons why you really want to lose weight and what it will mean to you and write them all down and keep it somewhere. When you are having a bad week or your resistance is low, you can get out your list and remind yourself why you are doing this and motivate yourself to carry on.
Avoiding WI is also quite a common post amongst those having a bad week who think they can avoid going and make up for it the next week. It is always a bad idea not to face up to what is really going on and I would urge anyone that they must get weighed and find a way to move forward and deal with these disappointing weeks as there are times you can be 100% but show nothing on the scales. A good way is to measure yourself right from the start and perhaps when a bad week pops up you can have a measure and where you can't see the pounds you can bet you will see the inches lost.
I hope this will give you something to go on and the only other thing I can say is whatever happens not to beat yourself up about a bad day if you do give in, draw a line under and start afresh the next day. Keep following this plan and you will get where you want to be. Good luck with everything
