Symptoms<\/span>

<\/strong><\/h4>

Increased energy and less nauseaMany women experience a decrease in nausea and an increase in energy levels, making it easier to resume daily activities.<\/p>

Abdominal growth<\/strong>The uterus begins to expand beyond the pelvis, which may make the abdomen appear more rounded.<\/p>

Increased appetite<\/strong>As nausea decreases, appetite usually increases. It is important to choose healthy foods and control portions to avoid excessive weight gain. <\/p>

Skin changes<\/strong>The “pregnancy glow” may appear due to increased blood flow and natural oil production. Some women also begin to notice the linea nigra (a dark line on the abdomen) or melasma (skin spots). <\/p>

Nasal congestion<\/strong>Increased blood flow and hormonal changes can cause inflammation in the nasal membranes, resulting in congestion or a stuffy nose sensation.<\/p>

Gum sensitivity and bleeding<\/strong>Hormones can make gums more sensitive and prone to bleeding when brushing teeth. Using a soft brush is recommended, and consult a dentist if bleeding is constant. <\/p>

Increased vaginal discharge<\/strong>It is normal for vaginal discharge to increase due to hormonal changes. As long as it does not have a bad odor or abnormal color, it is usually not a cause for concern. <\/p>

Constipation and gas<\/strong>Progesterone continues to affect digestion, which can cause constipation, bloating, and gas buildup. It is important to consume fiber and stay well hydrated. <\/p>

Occasional headaches<\/strong>Some women may experience mild headaches due to hormonal changes and increased blood volume. Resting, staying hydrated, and avoiding stress can help reduce them. <\/p>

Dizziness or lightheadedness<\/strong>Increased blood flow and changes in blood pressure can cause episodes of dizziness. It is advisable to avoid sudden position changes and stay well hydrated.

Baby Size<\/span>

<\/strong><\/h4>

This week, the baby measures approximately 7 to 8 centimeters long, similar to the size of a peach or large plum. Its weight is around 25 grams, although it will continue to grow rapidly in the coming weeks. <\/p>
