So I'm 15 weeks today and I'm not gaining any weight. If anything, I'm losing weight. I've lost 7 lbs since my last prenatal appointment which was a month ago. I was 120 but I'm down to 113. I have another appointment Monday. I'm just wondering if anyone has went through this also? I'm concerned and trying to eat as much as I can. But I don't have much of an appetite. And I haven't had morning sickness all that much either. Advice please?
