Thanks girls - I already use my exercise ball (can I still do situps etc - I know I've already had kids but I've forgotten), and I try to walk but it is difficult with my two kids (they are not walkers) and If I wont to walk it has to be before 5am or after 10pm at night, I dont mind that but its not the safest.
I don't care what I look like as such, more worried about the effects of being excessively over weight to bubs and me - I already have high blood pressure (not weight related but probably doesn't help) but I have never weighed this much. I am a bit of a deceiving person, I definately dont look as much as I weigh in kg's, in fact was 20kg's heavier than a friend who was 2 dress sizes bigger - but my kg's are alot, therefore my bmi is riduculous. I'm not a snacker - could cut down my meal sizes, am trying to eat healthy. I'm just a little anxious as I really want to relish in everything great this pregnancy.

I hope my question wasn't offensive and I probably should've worded it better, I don't not want to put on weight (baby weight is great) and I certainly don't want to starve myself or do my baby harm, just trying to do whats right!
