Im almost 15 weeks and have dropped almost 10 pounds. I can barely eat and my doctor, SO, and mother are really starting to get concerned. I take prenatals and drink plenty but Im lucky if I can keep a meal down a day. Im not naseous i just feel overly full everytime I eat. My stomach will be growling and i still feel so full. Also, when I am hungry all I can eat is fruits and vegetables. This is my first pregnancy and I want the best for my baby. What can I do to start gaining weight??
