Dont worry about it , continue counting calories and dont wory about the exercise u can get straight back to it as soon as your feeling up to it.
Maybe get some small dumbells when your sitting next to her and do few reps a day and squats. To keep your muscles toned. But dont worr 2 much about it soon as u get back in 2 it things will be okay
Or another option buy one of those body toners belt things that you can put on your abs , and also use it on your arms and legs and tone each area for 5mins a day. u can walk round with them on and do your day to day stuff whilst toaning and burning calories
Hope this helps
