• There is so much going on in your stomach right now. Your baby is a wildly growing ball of cells. This ball of cells is called a Blastocyst.
• After the blastocyst settles in the uterus, the part that will form the placenta begins to produce the pregnancy hormone called hCG. This hormone instructs your ovaries to stop producing eggs. It also triggers intense estrogen and progesterone production.
• HCG hormone is the reason why the pregnancy test is "positive". When a pregnancy test is done at the end of this week, the result will be positive. (If the test is negative and there is no period, you can try again in a few days.)
• Meanwhile, in the cavity that will form the amniotic sac, amniotic fluid begins to accumulate around the blastocyst. This liquid will keep and protect your baby in the weeks and months to come.
• Right now, your little blastocyst is taking in oxygen, nutrients, and excreting waste through a simple looping system of microscopic channels connected to tiny vessels in your uterus. Next week, the placenta will take over this task.

What is going on in your body step by step?

• A very important encounter took place inside you. The strong membrane of your egg has been penetrated by a single sperm and fertilized.
• A few days after fertilization, the egg descended into the uterus and began to develop there. A baby is about to come to life inside.
• You probably don't know you're pregnant yet. But maybe towards the end of this week, you may experience some light bleeding. This is called 'Implantation bleeding'. It happens because the fertilized egg passes through the uterine layer, which has high blood circulation. It is a light bleeding; can live.
