Baby Development

How is my baby growing?

Now you are entering your fourth week of pregnancy. Your baby is now a size of a poppy seed, which is about 2mm. Right now your baby is technically called an embryo. During this phase of the baby’s development, cells begin to develop into all of your baby’s important organs: the brain, heart, lungs, internal organs. The arms and legs also start to form. To provide protection, the amniotic sac starts to form around the embryo as well as the yolk sac. The yolk sac will produce blood and help to nourish the embryo until the placenta takes over that role. Your baby now has 3 distinct layers: the inner layer (endoderm), the middle layer (mesoderm) and the outer layer (ectoderm). The inner layer will eventually form the digestive system, liver and lungs while the middle layer will develop into the baby’s heart, sex organs, bones, kidneys and muscles. The outer layer will soon turn into your baby’s nervous system, hair, skin and nails.

Body & Life Changes

How is my body changing?

This week your embryo will attach to your uterus. This is called implantation.

Once implanted, your baby starts to produce a hormone called human chorionic gonadotropin (HCG), which helps to maintain the lining of the uterus. It also sends a signal to the ovary to stop releasing an egg each month, which stops your monthly periods. Some women experience slight cramping and spotting of blood during this week while implantation is taking place, and they may mistake this for the period as it often occurs around the time their monthly period was due.

HCG is the hormone that is measured in pregnancy tests. This week a pregnancy test will probably be able to detect your pregnancy! HCG also causes the symptoms of pregnancy, which can appear this week. You might be feeling fatigue, tingling or aching breasts, or nausea. These symptoms can easily be mistaken for your period. But by the end of this week, your expected period will not take place. Your pregnancy is well on its way!

What should I be concerned about?

You might be wondering if you are experiencing early signs of pregnancy. Here are some signs that can let you know you are pregnant.

  • Soft, pain and swelling breasts: Many women say they feel pain just like the pain in the menstrual cycle, yet more severely.
  • Fatigue: You may feel tired dramatically. Increasing concentrations of the progesterone hormone and how you attempt to have a baby can make you feel as if you have to run extra long distances after exhausting after a hard working day.
  • Frequent urination: As soon as you are pregnant, you may find yourself always hurrying to the toilet with an alarming frequency.
  • Sensitive to the smell: Many pregnant women are often overwhelmed by the smell of pregnancy. This may be a side effect of the estrogen levels, which rises rapidly in your body.
  • Loss of appetite: At this point, you throw the food out more frequently than when you get cravings. You may suddenly feel that the foods you once enjoyed and was happy while eating now become truly frightful.
  • Nausea or vomiting: Morning sickness usually does not begin within a few weeks pregnant. However, some women may still feel nausea before.
  • High temperatures: If you draw a graph showing the body temperature and it stays high for 18 consecutive days, you’re probably pregnant.
  • Bleeding or spotting blood: Some women will get red spots, red or reddish brown during their menstrual cycle. If you have pain while bleeding, call your doctor immediately as this may be a sign of ectopic pregnancy.

If you are feeling any symptoms, you can test with a pregnancy test.  A pregnancy test can test as early as the first day you miss your period.

Doctor Visits

What should I tell my doctor?

Let your doctor know if you have any signs or symptoms of pregnancy. If you have any concerns about any changes your body is going through, you doctor is the best person to guide you. This would be the best time to find an OBGYN doctor (a doctor who specializes in pregnancy and child delivery) that is best suited for you. Your OBGYN doctor will deliver your baby. It is important to find a doctor that makes you feel comfortable and always informed.

What tests should I know?

The only test you should know about at this time is a pregnancy test. If you didn’t use it last week, it might be a good idea to buy a few right now.

The pregnancy test may be confusing to read. It is not always clear for everyone. You might also need to test a few times to confirm your results.

Health & Safety

What should I know about being healthy and safe while pregnant?

Pregnant women cannot donate blood. Theoretically, donate blood during pregnancy can cause anemia iron depletion. In addition, blood donation has not been proven safe for pregnant women. So blood donation organizations usually do not allow pregnant women to donate blood. Also, mothers who just gave birth should not participate in blood donation activities. The Red Cross recommends that you should wait six weeks after birth. After this time, you can join regular donors, even if you are breastfeeding.

Most women who have had children can donate red blood cells, but for some people, the pregnancy may affect the ability to donate platelets. Blood from some women have antibodies after pregnancy can cause complications for patients receiving the blood. The blood donation center can test your antibodies before allowing you to donate platelets.
