I went for my 4d scan saturday at 28w1d and baby was measuring at 1015 kg or 2.3lbs. The sonographer said this was slightly below average. Got measured today (28w3d) with midwife and my FH was 26cm. She said this was "borderline" and if it was a fraction lower i would have been sent for a small for size growth scan. I didnt think much at the time when she told me because i had just had my blood taken and felt a bit woozy... but now when i think back to what i was told at the 4d scan and what the midwife told me today... do you think i should push for a growth scan?
