Your uterus has now grown to about the size of a grapefruit to accommodate your baby, which is about one inch long and weighs 4 grams. Now it may be time to make some changes in your wardrobe, as your favorite jeans may be a bit tight at this point.
The tail disappears this week and all the baby’s organs, muscles and nerves are beginning to function. Eyelids are starting to cover the eyes. The baby is beginning to look more and more like a human at this point. They can make a tiny fist, and suck their thumb already! They can make all sorts of facial movements, including frowning, swallowing motions and moving the tongue around.
The placenta is nourishing the baby now. Chorionic villi are a tissue that is part of the placenta. Since these cells are made of the same material as the baby, it can give very important information about the baby. CVS testing is typically done between weeks ten and twelve and will screen for birth defects and other abnormalities. CVS (or chorionic villus sampling) is typically done for woman over 35, or if you have a family history or genetic illness. This test has some risks, so be sure and talk with your health practitioner if you are considering this procedure.
