Cell-free fetal DNA represents extracellular DNA which originates from trophoblastic cells. However, the vast majority of cell-free DNA in maternal blood originates from the mother, with cell-free fetal DNA representing only 3% of the total cell-free circulating DNA in early pregnancy rising to 6% in late pregnancy.

Your baby at 5 weeks. The baby's nervous system is already developing, and the foundations for its major organs are in place. At this stage, the embryo is around 2mm long. The heart is forming as a simple tube-like structure. The baby already has some of its own blood vessels and blood begins to circulate.

Blood cells and vessel production in structures outside the embryo proper called the yolk sac, chorion, and connecting stalk begin about 15 to 16 days following fertilization. Development of these circulatory elements within the embryo itself begins approximately 2 days later.

Amniotic fluid surrounds the embryo and fetus during development and has a myriad of functions. Physically, it protects the fetus in the event the maternal abdomen is the object of trauma.

The umbilical cord is made up of one large vein and two smaller arteries. The vein carries the oxygen-filled blood from the mother to the baby. ... The cord inserts into the placenta so it's not directly connected to the mother's circulation.
