You are almost halfway through your pregnancy! Your belly already shows, and it is likely that you feel mild abdominal cramps occasionally, especially after changing your position. It is due to the stretching of the ligaments and muscles that support your uterus, since it is enlarged now.

The different sections of this article have been assembled into the following table of contents.

Symptoms to expect

During pregnancy, your heart has to make an extra effort in order for blood flow to reach the mother, the fetus, and the placenta. Due to this increased blood flow, you might experience heartburn and anemia during the entire pregnancy. Heartburn may scare you, but in the majority of the cases, they do not have consequences at all. In any case, we recommend that you consult it with your doctor, especially if it is accompanied by other symptoms or occur too often.

You may also notice an increase in the amount of vaginal discharge, due to increased blood flow in the vaginal mucus. Do not worry about it, it is a normal symptom.

Fetal development

During week 19 of pregnancy, millions of neurons are created in the brain of fetuses. This means that, at this point, his brain resembles yours more than ever. The central nervous system of the fetus continues developing, which means that his/her five senses have just started being active.

For example, he can notice your voice and heartbeats now. So, if you want to talk to your baby, he would be able to hear your voice even if you are not talking to him directly. In fact, he is able to distinguish it from other voices. The skeleton becomes thicker, too.

The roots of permanent teeth are forming under the milk teeth of your child, although they will remain inside the dental alveoli until ages 6 or 7, when they erupt. Dental alveoli are defined as sockets located in the jaws in which the roots of teeth are held.

By the end of this week, your fetus measures about 16 cm, and weights 200 g approximately.
