Pregnancy Calendar - Week 14
Amazing things are happening between your baby and the amniotic fluid. This week, your baby has begun to urinate into the amniotic fluid. This means the amniotic fluid has to replenish itself, about every three hours. For this reason, it’s vital that you drink lots of fluids to ensure a clean and happy womb. Your baby’s lungs are also ‘working’-they are ‘breathing’ in the amniotic fluid.
Hair is sprouting on the head, including fine little eyebrows. Lanugo, the fine, dark hair that grows over your baby’s body to protect the skin, also begins growing this week and will continue growing until just before delivery.
Reproductive developments are taking place. In boys, the prostate gland develops. In girls, the ovaries descend from the abdomen into the pelvis. Hormone production starts because the thyroid gland has matured.
Congratulations-you made it to the second trimester! Hormone effects are becoming apparent on your body. At this stage of pregnancy, your uterus will be about the size of a grapefruit.
