11 st week of pregnancy: urine production

Your fetus begins to produce urine, which will be released into the amniotic fluid. The bones of the foetus begin to harden, especially those of the pelvis, ribs, head, limbs and spine. Your baby's skin, although still thin and transparent, begins to thicken and become covered with fine hairs called lanugo. The sense of touch is refined for all parts of the body.
