4 weeks pregnant

by Richard Kozinski

It is high time you confirmed that you are pregnant.  Pregnancy syndromes, which can be present at the moment are: missed menstrual periods, hormonal changes, nausea and vomiting.  At the beginning you should take an over-the-counter pregnancy test, which detects the levels of the firstly produced placental hormone, hCG. It is also necessary to contact your gynaecologist or obstetrician, who examines your general health condition and refers to a lab test (blood and urine tests).

Your Baby

The heart of your baby is beating! This week is the beginning of the embryonic period.  This stage is enormously significant, since all of the organs start developing. Some of them begin functioning.  Now your child is called an embryo and its length is 4 mm - it is the size of an apple seed.

The primitive placenta has already developed.  Its cells are tunnelling into the lining of your uterus, thanks to this blood flows to the developing placenta and provides nutrients and oxygen to your baby.  Amniotic sac, which has also developed, will be a house for your baby. In turn, the yolk sac produces red blood cells and helps to deliver nutrients, until the placenta has developed and is ready to take over these functions.

It is worth remembering that every child is different, even during the embryonic period and babies can develop in their own rate.  Also, a pregnancy is  different for every woman and differences do not mean abnormalities. 

Guidelines for Mother

If you are certain that you are pregnant, remember to change your diet and lifestyle.  The fourth week of pregnancy starts a very intense growing period, so it is high risk for abnormalities, because brain, heart, muscle and tissues are developing.  You should avoid alcohol, drugs and medicines, which can affect your child's development negatively.  Try to have more relaxation.  You should also take some prenatal multivitamin with an appropriate dose of folic acid.  

Anxiety, exhaustion, mood changes, nausea and dizziness are normal syndromes  caused by hCG production. Additionally, your breast can become more tender. Some women notice a tingling sensation, too.  Most pregnant women find that their sense of smell changes and some odours cause nausea or even vomiting. It is why the first trimester seems to be quite uncomfortable and hard. Fortunately, most of the signs disappear when the next trimester starts.
