Morning Claire,
Do you go on the scales a lot?
I try to ONLY weigh once a week at my CDCs. I find that my weight fluctuates enough that I can show quite a gain at various points in the week, but come Monday morning and my weigh in -- I usually show a loss (not a lot -- it is going slowly, but still it is there).
Do you have Judith Beck's book? There is are a coupld of sections about weighing yourself and how you have to try not to scale hop (hard habit to break), and how you have "mentally" prepare yourself for your weigh in.
Your hormones could be affecting those scales, water retention, etc.
I am worried about "Madam". When is her next doctor's visit? Is her urine dark? Is she weeing as much as usual. Even though she is tiny -- if she is dehydrated she could be two pounds lighter.
I hope you have a better day and the headache has passed.
My DD is already dressed for the funeral service (her BFF's nan passed away) and has put a little package tissues in her handbag -- bless.
MM
