Thank you for the lovely welcome Mamalinz, I am due on 10th May 2012. Because of my rather potted uterine history - premature birth of my DS at 33 weeks, my miscarriage at 14 weeks, which was then followed by two D&Cs and a hysteroscopy (retained products, then Asherman's syndrome) the recommendation is not to go to an amnio as there is a higher than normal risk of miscarriage from the procedure itself. The fetal medicine doctor said that his cutoff is 1 in 300 for an amnio or CVS. I am going to discuss with my obs tomorrow and seek her view. What have other people on this thread decided?
