Microscopic and beloved

Most likely, you have only just made sure that you are pregnant after seeing two strips on the test. Okay, who are we kidding? Two strips on all 10 tests! Emotions are going wild in you, and in everyone you've managed to tell? Not surprising!

Meanwhile, a small ball of cells the size of a poppy seed finally entrenched in your uterus and divided into two parts: the embryo, which will become your son or daughter, and the placenta.

Despite the extremely small size, your tiny embryo is busy on home improvement. An amniotic sac (sometimes called the “bag of waters”) is formed around it, as well as the yolk sac, which will later be incorporated into your child's digestive tract.

The bubble with amniotic fluid is a tribute to evolution. The vertebrates that came out on land have lost the ability to spawn directly into the water, where the embryos can easily develop, not being afraid to dry out. Therefore, nature has made sure that in utero babies grow up in a comfortable aquatic environment. So for the coming months, your baby is a little fish.

The embryo has changed a lot since last week: now it has three separate layers of cells — building materials for different parts of the body. The inner layer, the endoderm, will turn into your kid's digestive system, liver and lungs. The middle layer, the mesoderm, will soon become your child's heart, genitals, bones, kidneys, and muscles. And from the outer layer, or ectoderm, the nervous system, hair, skin, and eyes of your child will form.

It is still quite microscopic, but it already feels your love.
