I had my 36 week checkup on Tuesday and the midwife measured my fundal height at being 40. So this means that I am as big as what I should be at 40 weeks which makes me 4 weeks early! Has anyone else had this and will it mean that baby will be really big? My first baby was 3.85kg. I have a caesar on 31 December and wonder if baby will run out of space by then.
