At the ninth week you already notice you are pregnant. If you have not told the good news yet you must decide whether to do it now or to wait a few more weeks.

Many women choose to wait until the third month of gestation, as it decreases of risk of suffering a miscarriage. Upon telling you are pregnant to your closest and dearest ones, you will receive their greetings and wishes, but also their advise, requested or not. You should consider that the person you need to pay attention to the most is your doctor.

Provided bellow is an index with the 3 points we are going to expand on in this article.

Changes in the embryo

The embryo, meanwhile, starts the differentiation of the urogenital and anal membranes, and the genital tubercle is formed. The liver experiences a remarkable development and forms the embryo's blood.

Physical appearance

The head is big, although the chin is barely noticeable. The brain is visible trough the very skin, showing all the blood vessels. The eyelids, now formed, are composed of the skin that covered its eyes during the previous weeks.

Some joint regions appear, being the wrists the first to do so, followed by the ankles. The hands and feet start to move, but you will not feel it. The hands have now a better shape and the fingers will start to separate from each other.

The foetus at this point starts to resemble more and more to a human being, from the third month onward, you will be able to get a rough idea about the aspect of your baby.

The embryo will be 18 mm long by the end of this week.

We make a great effort to provide you with the highest quality information.
