Im 13 almost 14 weeks and since 9 weeks I have no appetite. I barely notice when my stomach is growling. I don't get nauseous but it's barely possible for me to eat. It's like im no longer capable. I've couldn't even finish a full meal today and it's all I ate. My weight keeps going down and it's concerning me. What can I do to eat more to make sure my baby is getting the nutrients they need??
