Baby Development

How is my baby growing?

You are now 13 weeks pregnant. Your growing fetus is about the size of a green pea, approximately 7 cm from head to toe and weighs about 30g.

This week there are many changes in your baby. Changes may include the umbilical cord moving towards your baby’s stomach. This umbilical cord is attached to a growing placenta that is providing your baby with all the essential needs. Your placenta weights about 30 grams now but will grow to become close to 900 grams. Your baby’s vocal chords are also forming. You won’t be able to hear any sounds yet but soon you will hear these vocal chords once the baby is born. Your baby may be able to put his thumb in his mouth.

Body & Life Changes

How is my body changing?

Your pregnancy symptoms are probably starting to subside or even disappear. You will soon start to gain more energy and feel more like your regular self. If you still are experiencing some nausea and fatigue, rest assured these symptoms will lessen within the upcoming weeks.

Unfortnately, this does not mean you will be symptom free. One of the symptom that you may be experiencing is an increase in vaginal discharge, also known as leukorrhea. Your discharge may be thin, milky and odorless. Don’t be alarmed. This is normal and is usually caused by high levels of estrogen, another type of pregnancy hormone. With the increased blood flow to the pelve area, an increase in vaginal discharge is triggered to protect your birth canal from infection. If your vaginal discharge starts to smell and change in color, let your doctor know immediately. This can be a sign of an infection.

What should I be concerned about?

You may be concerned about exercise during preganancy. There are some things you should know before starting a new exercise routine. Here are some helpful tips:

  • Keep your exercise intensity at a level where you can talk without feeling short of breath.
  • Chose low-intensity exercises and rest if you start to feel short of breath, exhaustion or dizziness.
  • Modify your exercise routine as your pregnancy progresses. Remember that your baby will add more weight to your body. To prevent any injury, you should listen to your body to know how much you can handle.
  • Pay attention to the changes in your body. Stop any exercise that is causing pain or exhaustion.

Doctor Visits

What should I tell my doctor?

If you are having trouble breathing, let your doctor know. This can occur when you walk up the stairs at work or at home. Usually, this will only last for a few minutes. But if your breathing is worsening or you have chest pain, contact your doctor or seek emergency care immediately. When you can’t breathe, less oxygen is entering your blood, leading to lack of oxygen to your baby.

What tests should I know about?

During your normal doctor’s visit, your doctor will perform the routine screenings. These will include the following:

  • Measure your weight and blood pressure;
  • Check the sugar and protein in the urine;
  • Check the fetal heart rate;
  • Check the size of the uterus by external palpation;
  • Measure the height from the bottom of the uterus;
  • Check whether your hands and your feet have swollen or varicose veins or not.

Tell the doctor about any symptom that is causing discomfort. It may be a good idea to create a list of all your questions and concerns before your doctor’s visit.

Health & Safety

What should I know about being healthy and safe while pregnant?

When you are exercising, it is important to be safe. It is good get your heart pumping but it can be harmful when your heart rate is over 140 beats per minute. The best way to measure the intensity of the exercise is to listen to your body’s signals. It is good to sweat but when you start to have trouble breathing or can not talk during your exercise, that’s when you need to stop. Choose physical activities that are low-intensity such as swimming or walking. You can also have mini breaks in between. This will give you time to rest and prevent any potential harm to you and your baby.

So next week the fetus will grow like what?
