i would not do amnio. 20% risk rate of miscarriage. sonograms and blood test i did and they were great rule outs. i had a healthy baby girl at 38. honestly at 30 i would not even bother.
The nueral transluency needs to be soon like before 12 weeks, so you better get it now if you want it. The level 2 as 18-20 weeks. We did both with blood work at the first visit
