look good to me, but as others have said, they are just numbers and they are enough to make us crazy!
I would wait to see what the Materniti21 results come back with and then make your decision. I had an amnio with my first b/c my numbers were not good and I needed definitive results that all was okay, so I didn't spend my whole pregnancy worried and filled with anxiety. Of course the risk of m/c with the amnio frightened me, but the specialist at my clinic had way better rates than the average. These decisions are so difficult and I wish you the best in whatever you decide.
