What you can expect for you and your baby in your 4 weeks of pregnancy…
Now that you are 4 weeks pregnant, if might be time to purchase that home pregnancy test, or schedule an appointment with your doctor for a blood test to confirm that you are expecting.
Your baby at 4 weeks pregnant
At four weeks pregnant, your baby is not quite.3mm long and about the size of a poppy seed. The blastocyst has attached itself to your uterus wall and is now ready to split into two, half of which is the embryo and the other which will form the placenta. The placenta will supply your baby with the nutrients it needs to survive, grow and develop the next 8 months, while also disposing of waste. Until the placenta is fully formed, the embryo is protected by a yolk sac, which produces blood and provides nutrients. The amniotic sac is forming to protect the baby until birth.
At 4 weeks pregnant the brain and central nervous system are beginning to form as the neural tubes are developing. The heart and circulatory systems are starting to take shape and as well as the lungs and intestines. As the vascular network is developing, it aids in delivering oxygen, blood and nutrients from your body to your baby’s via the umbilical cord.

If at this point you suspect that you are pregnant, and have a positive result on a home pregnancy test, you should schedule your first prenatal visit with your doctor to for confirmation. Your doctor will ask you questions regarding your health, family history, diet and habits. He will then prescribe the proper prenatal vitamins and other supplements such as folic acid you should be taking. You will schedule your 
prenatal appointments for the remainder of your pregnancy. It is important that you keep these visits and strictly adhere to everything your doctor tells you.
