Hi - just looking for someone who is in same position. 
Had routine mw check up and she said I'm measuring lfd and baby is big.  I was 34+3 measuring 36 she has referred me to a consultant which is booked in for 2nd June. Will they scan me to check? Everyone keeps telling how I don't look big at all, now I'm worried I'm going to have a big baby!! I'm in uk btw
