Hcg double expected

Chel

So my bloods came back as higher risk for downs, nuchal translucency was 1.2 which is perfect, baby measuring perfectly on time at 12w3d. The nurse said my hcg levels are double what they’d expect at this gestation and obviously at 38, my age is a factor.

My hcg has been high all through pregnancy, I got my first positive at 7dpo.

Should I be worried?
