I had my 28 week scan yesterday and both babies are estimated 2lb 3oz which has dropped off the growth charts, less than 3rd centile. Naturally, I’m worried. I have a scan with fetal medicine in 2 weeks time. What does this mean for my babies? Is there something wrong with them? I’m used to having big babies (over 9lb), so these tiny little things are way out of the norm for me.
