The crown-to-rump length of our baby is about 1 1/2 inches. He weighs about 0.18 ounces. The placenta is now producing progesterone which helps to make nutrients for your developing baby. Our baby has passed the stage when he is most susceptible to damage. By the end of this week, the danger zone for congenital abnormalities has passed. The plan for our baby’s body has been completely laid down by now. Further growth and cell division will build on this plan. Taste and tooth buds have appeared. Our baby has recently developed fingers and toes which are now well-formed. Ankles, wrists and the inner ear have formed. Our baby’s nose is flat and his eyes are far apart. His eyes, ears, mouth and nose are all recognizable. The tail is disappearing. Our baby is moving around the amniotic sac, and moving his feet and ankles. I still don’t feel these movements but may be able to see them on an ultrasound. Blood is circulating through the arteries and the vein of the umbilical cord. The brain of our baby is developing at a phenomenal rate. About one quarter of a million new neurons are produced every single minute at this stage in my pregnancy. (no wonder I’m tired!)
If our baby is a boy, his testes, though they are not even clearly visible, are already producing testosterone.
Your uterus is now about the size of an orange, but you still don’t “show”. (YEAH, RIGHT!!)
You may be (MAY be?) having mood swings, feeling happy and elated one moment, crying the next. This is perfectly normal. (Could someone please clue in my husband?)
