Hi Lisa
I know it can be disheartening whenyou don't see the results on the scales - I've been there lots!!
Like Wobbles suggested, take your measurements and keep doing it at regular intervals (every 2-4 weeks or so maybe?) and also try something on that you wore before you started with Slimming World and see how it fits now.
As you are doing so much exercise my first question would be have you dramatically increased your exercise recently? That has a huge impact on your scales results.
If you have gone from doing zero exericse when you started SW, to doing all of the above mentioned exericse each week your bosy will still be getting used to what you are doing. Exericse causes your muscles to tear and then you get a build up of water whilst they repair themselves.
I am not in anyway suggesting you stop exericsing, you're doing fantastic with it, so absolutely keep it up! Just be aware that it can have an impact on your scale results.
As long as you make sure you are sticking to the plan, you will see the weight go, but maybe not as quickly as you would like.
You could always try starting a food diary on here and we can help if you need it
