Your baby now measures about 3.1 inches (8 cm) from crown to rump. Because the amniotic fluid around the baby transmits sound, the baby will gradually start to hear her mother-to-be’s voice and heartbeat. The hair on baby’s head and eyebrows is becoming coarser. If the baby is going to have dark hair the pigment cells in the hair follicles start producing black pigment.

Your baby’s ribs, blood vessels and retinas are clearly visible through her papery skin. Lanugo are very fine hairs that help the baby to regulate body temperature and are now starting to cover the baby’s skin. Body hair mirrors the pattern of the skin to form shapes that look like fingerprints all over the body.

Your heart is also beating slightly faster than usual, from about 70–75 beats per minute before you became pregnant to about 85–90 beats per minute towards the end. Your blood volume continues to increase throughout your entire pregnancy.
