Your 5th Week
If you have no period and a positive test result, you're going to have a baby!
Embryo at 5 weeks
7. The amniotic sac is a fluid-filled sac that cocoons the developing embryo.
8. The chorionic cavity surrounds the amniotic sac and is bounded by a membrane called the chorion.
1. The embryo now measures 0.09 in (2.5 mm).
2. A fold down the back of the embryo marks the beginnings of the spine.
3. Chorionic villi reach into the wall of the uterus to form the placenta. The villi contain blood vessels that tap into your body's blood supply to access nutrients for the baby.
4. The umbilical cord connects the baby to the developing placenta. At first it is rather short and has yet to develop any coils.
5. Embryonic tissues are already forming into a structure that will become the heart.
6. The yolk sac nourishes the embryo until the placenta is established and can provide nutrients through its blood supply.
When your pregnancy is confirmed, it's natural to experience a mixed bag of emotions-excitement, disbelief, joy, and anxiety. Everything is about to change forever for you and your partner. Give yourselves time to take in the big news. You may not feel pregnant yet, but momentous changes are taking place in the hidden world of your uterus. Step by step, the building blocks of life are being set in place.
