4 Weeks Pregnant

In Week 4 of Pregnancy your baby is about ½ to 1 mm It is thus very important that the mother takes utmost care of long. Your body is experiencing a huge transformation as the tiny ball of cells that will become your baby transforms into a multi-layered embryo. This change may cause symptoms like cramping, bloating and emotional highs and lows, similar to premenstrual symptoms.

Development of Baby

The amniotic sac and yolk sac develop during this week. The amniotic sac and yolk sac fill with amniotic fluid which protects the embryo. The yolk sac produces blood and helps nourish the embryo until the placenta takes over.

Your baby’s vascular network (arteries, veins and capillaries) is growing and helping to transport blood, oxygen and nutrients from you to your baby by way of the umbilical cord.

The heart is beating, blood is beginning to pump and organs are starting to develop.

Advice

At this stage the tiny embryo starts to produce human chorloric gonadotropin (hCG), the hormone produced after conception, enabling you to confirm, by means of a pregnancy test, if you are pregnant.

If the results are positive, call your healthcare practitioner and schedule an antenatal appointment.
