Your pregnancy: 3rd week

What is going on in your uterus now? It works really hard for your baby that is under development and it is only a small ball containing several hundred cells that are multiplying rapidly .
This “ball of cells ” (also known as a blastocyst ) takes place in your womb and the part that will develop into the placenta starts to produce HCG (human chorionic gonadotropin – hormone of pregnancy ) , which tells your ovaries to stop creating eggs and activates increased production of estrogens and progesterone. HCG is a hormone that your pregnancy test will give a positive result .

Meanwhile, the amniotic fluid begins to collect around your ball of cells (blastocyst) in the gap, which afterwards becomes amniotic sac. This liquid will be a “cushion” for the weeks and months that follow. At this point, your blastocyst is receiving oxygen and nutrients through the primitive circulatory system made of microscopic tunnels that connect with your baby’s blood vessels in the walls of the uterus. The placenta is developed enough to take over this role until the end of next week.

Early pregnancy symptoms:

Your Body in Week 3:

The key meeting takes one single sperm that managed to pass through the solid membrane of your egg and fertilize . A few days after conception , the fertilized egg makes room in the lining of your uterus and begins to grow . It is your baby in the making ! Maybe you still have no exact information as to whether you are pregnant or not, and it is possible to see the faint bleeding .

If you notice small dots or bright red blood on the panties , then there is a chance of bleeding caused by implantation . It occurs when the embryo attaches to the uterus ( a process that started last week or 6 days after fertilization ) . In any case , only a small percentage of pregnant women experience this symptom of pregnancy .
