Mom, I'm like a cabbage (39.9cm, 1319 grams)
My brain reaches another milestone - it can effectively regulate body temperature through controlling blood circulation and heat production. Fatty tissue grows at an accelerated pace, providing crucial thermal insulation. Lanugo gradually disappears from most of the body, remaining mainly on back and shoulders. Bone marrow takes complete control over producing all types of blood cells. Fingernails grow to fingertip ends and sometimes beyond. If I'm a boy, testes have entered the scrotum in 85% of cases.
Remember mom, every child develops at their own pace and has their unique timeline. If you have any doubts about my development in your belly, consult with a doctor.
