5. All of the following women can be at risk of SGA except

6. SGA birth, particularly when severe , is characterised by failure of trophoblast invasion of the myometrial uterine spiral arteries and reduced uteroplacental blood flow. However reduced endovascular trophoblast invasion of decidual spiral arteries has been associated with the same waveform abnormalities as early as how many weeks of pregnancy?
