Just found out I'm pregnant - only just 3 weeks but have been dieting for the last 5 weeks and lost half a stone. I don't starve myself (I eat porridge for breakfast, soup and a yogurt for lunch and a healthy dinner). I really don't want to pile loads of weight on during the pregnancy but don't want to harm the baby obviously and I'm irrationally scared of miscarrying again after mc in February. Anyone been here and have any tips or advice?
