Mom, I'm like a lime (54mm, 14 grams)

All major organs are formed and beginning to function in a coordinated manner. My sex is already genetically and hormonally determined - XY or XX chromosomes control hormone production that shapes my sex organs. I can already make sucking movements, swallow amniotic fluid, and even hiccup. Bone marrow takes over some blood-forming functions from the liver and begins producing white blood cells. My kidneys produce about 7-14 ml of urine daily. The grasping reflex develops - if you touched my palm, I would close my fingers around it. My heart pumps about 28 liters of blood daily through the developing organism.

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.
