I am 18 weeks pregnant today and to date have only gained 4 lbs. I am getting very worried over this, typicall midwife/GP says wait till scan (this is still 3 weeks away). When i had my last midwife appointment 3 weeks ago she did say the height of my fundus was short, it was 2 cm less than the number of weeks it should have been. This is my third child and with both the others I had gained more weight by now, with my second child I had put on 10lbs by this stage. I am eating very well, enjoying to many biscuits I would say. has anyone else had this problem with lack of weight gain and did everything turn out fine. I think I have felt the baby move allready and at last check up the heartbeat was fine. Help, Am i paranoid or is this usual when you are running around after a young one allready. I long to look pregnant and not just at that slightly chunky podgy stage I have been stuck at for months now.
