I had actually lost a kilo when I went to my last ob appointment. He didn't seem worried and I was told that maybe I'm just eating healthy. I haven't been dieting but when I weighed myself yesterday afternoon I was down another half kilo (it's been 2 weeks since my appointment). I was carrying a bit of weight before I fell pregnant - I was 71kg now I'm 65.8kg and totally all out front with bubs. Although, I did have pretty bad morning sickness for the first 15 weeks.
