I'm down 8lbs on my pre pregnancy weight!! Had terrible nausea that put me off all food practically for about first 17 weeks, had lost 10lbs by 19 weeks but finally gained 2lbs of that back last week!!
Am classed as obese, with a bmi of 34 (pre pregnancy) so a little bit of weight loss for me is nothing to worry about, plus baby's growing well (currently averaging 2 days ahead!!)
