Being Pregnant :: Calendar

	Week 9: Your baby is now approximately 13-17 mm in length or about 0.51 - 0.66 inches. It weighs only 1 gram! Gonads have become testes (for boys) or ovaries (for girls). Baby will move away if touched through the uterine wall, and can spontaneously move as well. Ossification (hardening) of the bones continues.

	Week 10: The baby is now called a fetus. The average length is approximately 27-35 mm or 1.06-1.38 inches, and the weight is four grams, or about the weight of four paper clips. Tiny toes have formed now. The eyes are largely open, but soon the eyelids will fuse and stay that way until 25-27 weeks. External genitals are beginning to differentiate. External ears and the upper lip are completely formed.

	Week 11: If you have seen pictures of babies at this stage you will notice that the head is about 1/2 of the body size. This will change as the baby grows. The iris (colored part of the eye) will begin to develop this week and fingernails will start to appear. The baby weighs about seven grams.

	Week 12: The baby's brain is not the same size as it will be at birth, but it does have the same basic structure. Your baby has its reflexes now. The fetus weighs about 14 grams now and is approximately 3.54 inches in total length.
