20 Weeks Pregnant - from Visembryo

Week 18 Post Fertilization...

A dramatic growth period for the fetus.

HEAD - Fetus has phases of sleep and waking and may prefer a favorite sleep position. Temporary hair called lanugo appears on the head. Lanugo may fall out in the second week after birth, allowing fine scalp hair to grow. Eyebrows begin to form.

SKIN - Brown fat (colored by capillary growth) coats neck, chest and crotch areas around the lymphatic system. The vernix (consisting of dead skin, lanugo cells, and oil from glands) is now clearly formed and visible covering the skin.

PLACENTA - Placenta is fully formed and grows in diameter though not in thickness.
