As the title says really. I was gaining steadily at about the right rate but I've noticed that my weight has hit a plateau and hasn't shifted for about three weeks. I am eating OK but not a huge amount because of chronic nausea and heartburn. Baby is fine and very active. I am having growth scans every month and so far the baby has been spot on - presumably as long as he is growing well my weight is not so important? or should I mention it to the midwife?
