Suspecting Pregnancy during 4 Weeks Pregnant

Overview

At 4 weeks pregnant, you may still not be aware that you’re pregnant. However, your little tenant is now at home inside your womb. At this point, your baby is starting its embryonic period wherein it will start to grow its organs but not all will begin to work. Your baby at 4 weeks pregnant is now an embryo, about 0.078 inches (1.98 millimeters) in length, similar size to that of a poppy seed.

Starting this week until 10 weeks, the organs of your baby will be on its developing stage. This is also the time that your baby is vulnerable to risks that will affect his development.

As your future baby or the small blastocyst reach your uterus from the fallopian tube, it has now already settled on your uterus or womb lining, thus implantation occurs. After that, the small ball of cells will break into two parts. The first half is your baby, the embryo, while the other half will develop the placenta that provides nutrients and discards wastes of your baby until birth.

Your Baby’s Development while You're 4 Weeks Pregnant

This week during 4 weeks pregnant, your baby is now an embryo, having two layers known as epiblast and hypoblast. These two layers will develop your baby’s organs and body part. The primitive placenta consisting of two layers, cells are tunneling into the lining of your uterus, living spaces for your blood to flow, for the placenta will become equipped with the ability to provide nutrients and oxygen to your growing baby.

Already formed inside your body are the amniotic sac which encloses your baby, amniotic fluid which serves as the cushion of your baby while growing, and the yolk sac which supplies nutrients and red blood cells to your baby connected to his digestive tract until the placenta is fully developed and functional.

Your little embryo has also developed its three main layers of cells that will soon become the major body parts of your baby. For the embryo’s first layer, the inner part is called the endoderm which will become your baby’s digestive system, lungs and liver.

The second layer, known as mesoderm, will become the kidneys, sex organs, bones, muscles and heart. While the third layer, called ectoderm, will become the nervous system, eyes, hair and skin of your baby. The brain and the central nervous system are starting to take shape at the same time, the neural tubes are developing. Arm and leg buds are also forming, although they are not clearly distinguishable.

The vascular network is also growing and working to transfer blood, nutrients and oxygen from mother to baby with the use of the umbilical cord. The heart is starting to beat and is beginning to pump. Your baby’s characteristics, such as hair color, sex, eye color, and more have been determined because of its chromosomes.

What's up this Week

How's your baby

While your baby is developing, the pregnancy hormones continue to produce chemicals including chorionic gonadotropin or HCG, which is present in your blood 11 days following your conception. It comes from the cells and will turn into the placenta.

How about yourself

This week, your body is preparing for what’s coming. However, some women are not feeling these changes while some relate pregnancy symptoms to PMS (if they are not aware of their pregnancy or until they came to the point of conception). The common symptoms are mood swings, bloating and cramping. But the early signs of pregnancy are having missed your period and having tender breasts.

Other symptoms women experience during this week are feeling nausea, heartburn, frequent urination, constipation, backache and lower back pain, extreme fatigue, hot flashes, shortness of breath, surge of emotions, sore breasts and nipples, light headed, sensitivity to smell, strange taste on their mouth and feeling nothing. Not all pregnant women experience the same early pregnancy symptoms.

Also, you may possibly see some light flow or spotting more or less the time that you typically have your period, and that is what you call breakthrough bleeding. Do not panic when you see this. It is normal however, it is always best to get your bleeding checked by your health care provider. Some also have an increase in vaginal discharge, normally caused by the egg burrowing into the uterine lining. Others are not experiencing spotting though.

Your basal body temperature, which is your body temperature when you are completely at rest, will remain high. There is a surge of blood flow to your breast, thus it is sore and tender. This increasing level of estrogen in your body also affects your sense of smell, which makes you sensitive to a certain smell. You may begin craving certain foods, and interestingly those foods that you formerly enjoy will start to taste different

What to Do when 4 Weeks Pregnant

If you missed your period, experiencing irregular period, or even experiencing the early symptoms of pregnancy, take pregnancy test if you’re suspecting you are pregnant. Now, if you receive a positive result, make an appointment with your doctor. However, they may wait to see you until you are 8 to 12 weeks pregnant. If negative, wait for another week to take the test again.

For women who already confirmed about their pregnancy, this is now the time to take folic acid supplement. Folic acid prevents and gives protection to your baby from birth defects especially on spinal and neural tube problems. Your health care provider may advise you to take 400 micrograms (mcg) of the folic acid supplement daily.

When it comes to your eating habit, at this point, you should stop from drinking too much alcohol and smoking, excessive caffeine or even taking recreational drugs. Whatever you are taking in, eat or drink, your baby is also taking everything too. This week is also crucial to your baby as it is the beginning of his development. For healthy food and diet, eat more vegetables and fruits for nutrients. You may also consult with your health care provider to make sure none of your medications and the food you eat is harmful to the fetus. Now that you’re 4 weeks pregnant, thinking the health of your baby should be prioritized especially when you’re on the early signs of pregnancy.
