Hi just wondering if anyone has any experience of what I have been told by the doctor today. I'm 31+5 but baby is measuring big in particular the head is greater than 99percentile,overall measuring at 34+5 weeks but head circumference is 36+3. I've been told I have polyhydramnios and also now aswell placenta previa. Very worried more than anything that something is wrong with the baby now due to large head. I have been tested twice for GD and that's normal. Going to see the doctor on Thursday but can't put my mind at ease that something is wrong now. Thanks so much.
