It freaked me out at the time. I was in tears when they told me. My age related risk is normally 1:88, my NT scan was very good, but my blood results were horrendous. A week later I felt much better. I would obviously still prefer our baby to be a picture of health, but if it isn't, we are ok with that. We want to be parents and are not the youngest (fertility wise that is of course!! At heart we are super young!! ). After three years of trying, an ectopic and a miscarriage, this one has decided to stick around. It might be the only one we might be able to have. I am just excited that I will be a mum.
Don't feel silly, because your risk is lower than mine. We all hope that we get better odds than our age related averages.
The scan on Monday is the anatomical scan, I'll be 19.5 weeks. So we'll see if we learn a bit more about bubs.
