13 Weeks Pregnant symptoms

Get used to fatigue

Pregnant women get used to enduring fatigue to feel that pregnancy fatigue no longer exists like the previous feeling, and this is because the body has adapted to the situation.

Increased appetite for food

At the beginning of pregnancy, a pregnant woman may find herself not coming to food or not smell food because of the changes that occur to her. Still, in the thirteenth week of pregnancy, the fetus’s size increases, which is evident in the abdomen’s prominence, and this is because the mother needs more nutrients needed for her to nourish her and her fetus.

Burning sensation in the chest (heartburn)

The most common cause of heartburn in the thirteenth week of pregnancy is the relaxation of the muscles that are at the top of the stomach due to the pressure of the fetus and the increase in its size, which helps the acid in the stomach reach the esophagus, and this leads to a feeling of heartburn.

Increase in vaginal secretions

The white vaginal secretions increase during this period. This helps protect the cervix from bacteria and maintains the balance of beneficial bacteria in the vagina, which reduces the incidence of infection.


At times, the desire for intimacy increases due to blood flow to the genital areas, and sexual desire may also decrease in the thirteenth week of pregnancy.


Constipation may be one of the most prominent symptoms of pregnancy in the thirteenth week due to fetal pressure and muscle relaxation that helps in excreting waste, which leads to constipation, and helps to eat more fruits and vegetables that contain fibers that help the excretion of waste, and helps prevent reducing caffeinated drinks Increase your intake of fresh juices and water.

Dizziness or fainting

You may need more time when changing position from sitting or sleeping to standing, and you may feel a little dizzy.

Visible veins increase

The appearance of veins on a pregnant woman, especially in the abdominal area and on the sides, increases, but it disappears after childbirth and appears due to the increase in the fetus’s size.

13 Weeks Pregnant Ultrasound

When you become 13 Weeks Pregnant, an ultrasound can tell you a lot about your baby’s growing rapidly. This is when you get to know the truth, and you can’t wait to see the fetus during the ultrasound results in the thirteenth week.

Thanks to technology, you don’t need to wait long to get a glimpse of your little one. An ultrasound provides you with a picture of a fetus in your abdomen. And if you are in 13 Weeks Pregnant, you will be able to see it very well.

Being 13 weeks pregnant, why is an ultrasound necessary?

Reasons for performing an ultrasound scan:

  • You will begin to get to know the fetus’s body parts because this happens as your little one grows and the organs appear more defined.
  • The 13-week examination provides the doctor with an idea of ??the baby’s gender.
  • The ultrasound of the fetus at the thirteenth week also provides a clearer picture of the developments.

How to prepare for an ultrasound scan?

This is one of the most crucial ultrasound exams during pregnancy. Your doctor will advise you to drink plenty of water before the examination because it is essential to keep your bladder full during the ultrasound. This will help the technician discover a more transparent image of the fetus in your abdomen.

How long does it take to have an ultrasound in the thirteenth week?

The examination at the thirteenth week can take between 15 to 30 minutes, and it can even take up to 45 minutes if the child is lying in an awkward position. This also depends on the expert conducting the test and the position of the baby in your tummy.

How is an ultrasound done in the thirteenth week?

The process you need is straightforward.

  • First, the technician puts a little bit of jelly on your stomach.
  • After that, the transducer is used on your abdomen. The purpose of applying the gel is to ensure there is good contact between the skin and the transducer device.
  • The device is set based on the image of the child that appears on the screen.
  • You should not be anxious because there will be no pain during this process. You may feel some pressure during this procedure.

What can be seen on examination?

This scan taken that week will show you subtle details that you were unable to see in the first months of pregnancy. During this stage, the things identified in the fetus are the heartbeat, the physical development of the body parts, the shape of the baby, and much more.

On previous scans, you were wondering why the baby’s head was more prominent compared to the rest of the body. However, this time you will feel at ease. You will notice the size of the growing head is proportional to the body.

The examination will also indicate any abnormalities that appear in the child and other developmental details. During an ultrasound examination at the thirteenth week, Down syndrome can be detected by identifying the fluid in the back of the fetus’s neck.

What if any abnormalities are found on examination?

If problems are discovered during the ultrasound, your doctor will talk to you to clarify the situation. Sometimes, doctors will order a few other specific exams or tests to check the abnormalities’ extent.

 An ultrasound scan helps you communicate with your little one in your tummy. You feel like life is inside you, but now you will see your baby grow and come to life. These are important moments in your pregnancy journey. If abnormalities are detected, do not let them disappoint you at this point. Instead, you can talk to your doctor and see what you can do about it.

Nutrition at 13 Weeks Pregnant

“How many calories should we eat?”

It is vital to maintain a balanced diet rich in vitamins, minerals, and nutritional compounds at this pregnancy stage. Starting in the second trimester, you should add about 300 calories per day on top of your regular daily meal. This addition can be made from 2 slices of bread with 3 tablespoons of 5% cheese and 1 vegetable.

Here’s a reminder of the most recommended foods at this point:

Vegetables and fruits – full of vitamins and minerals, low in fat, and contains beneficial dietary fiber.

 Tip: Vary the colors of the fruits and vegetables you eat because different colors contain different vitamins.

Protein-rich foods – low-fat meat, legumes, and low-fat dairy products are examples of protein sources that will support the fetus’s growth.


  • Uncooked eggs, meats, poultry, and fish, including processed meats. Avoid foods that contain raw eggs. Processed mayonnaise is usually made from pasteurized eggs and is therefore considered safe to consume.
  • Unpasteurized milk products such as soft cheeses such as feta, berry, and camembert – unless they are labeled as pasteurized.
  • Large fish such as mackerel, white tuna, and a slice of tuna are high in mercury. Avoid it during pregnancy, preferably salmon. Canned tuna is also safe to consume.
  • Sushi – never eat it. It is recommended to abstain from uncooked fish and sushi.

These foods can contain dangerous germs that may lead to illness, vomiting, and diarrhea in the expectant mother, and in rare cases, even to a miscarriage.
