Bleeding during pregnancy can cause maternal anxiety and emerging evidence suggests that it may be associated with poor fetal and maternal outcomes (Sotiriadis A et al., 2004) Nuchal translucency is a collection of fluid under the skin at the back of baby's neck between 11 weeks and 14 weeks of pregnancy or when baby measures between 45mm and 84mm (Nicolaides 2011).
