I want to preface this by saying, while I've gained very little weight, I've also been 180-190 lbs for most of my teenage/adult life so I don't think it's too big of a deal. I'm currently 21 weeks pregnant and had an appointment on Friday where it turns out I lost four ounces between then and my last appointment, which was four weeks earlier. (187.6-187.2). I'm literally right at my pre-pregnancy weight. I lost about 10 lbs during my first trimester due to being sick constantly. I'm showing and all, and baby is healthy, so should I be worried? My OB wanted me to gain only 15 lbs throughout my whole pregnancy, as I'm diabetic. (My numbers have been absolutely perfect thus far) and she hasn't mentioned my weight. Baby is in 48th percentile for growth in case that's important as well per my anatomy scan.
