I have a question. I'm 10 weeks and 5 days, but since the start of the pregnancy I've lost almost 7 kg. I'm very nauseous—almost everything makes me sick; I only eat fruits and vegetables, and I can eat boiled potatoes with the skin on. I'm very worried that something might happen to the baby because I'm losing so much weight. I also take vitamins.
