Here are a few symptoms you may experience this week:
- Weight gain: By the 31st week, the weight gain should be as follows (10):
|Body weight||Normal weight||Overweight||Obese|
- Shortness of breath as the diaphragm is pushed upward by the growing uterus. Breathing exercises can help you get relief.
- Braxton Hicks contractions are irregular, less painful contractions that help the body prepare for labor. Drinking plenty of water and changing your positions can relieve the discomfort.
- Frequent urination due to the pressure exerted by the growing uterus on the bladder.
- Backaches because of the burden of carrying the extra weight of the baby.
- Headaches due to the hormonal fluctuations, stress, or dehydration.
- Diarrhea as the hormonal changes can slow down the digestion process. You could also become sensitive to certain foods, which can lead to diarrhea. In such a case, drink plenty of water and stay hydrated.
- Clumsiness due to to the postural changes and a shift in the center of gravity of your body.
- Insomnia because of body aches, heartburn, and frequent urination.
- Forgetfulness due to stress and hormonal changes.
- Round ligament pain as the abdominal ligaments and muscles stretch.
- Edema of the feet and hands, which swell due to water retention in the body.
- Varicose veins because the growing uterus applies pressure on the on the veins that carry blood from your legs to the pelvic area, restricting proper flow.
- Hemorrhoids develop near the rectal area due to pressure exerted by the uterus on the veins. They are painful and itchy.
- Sciatica – when the growing uterus puts pressure on the sciatic nerves, you experience excruciating pain in the back and at the back of the legs.

Changes In The Body At 31 Weeks
Here are some physical and emotional changes that occur in your body:
- Due to the hormonal fluctuations, the nails become dry and brittle and could break easily.
- Yellow liquid, called colostrum, starts leaking from the nipples.
- The bump is bigger as the baby is growing in size. If you are carrying twins, then the belly looks more bulged. The linea nigra gets darker and prominent.
- The areolas get darker, and the nipples become erect and hard.
- The stretch marks are more prominent with the expanding belly.
- The blue veins are visible around the breasts and the thighs, due to the increased supply of blood to these areas.
- Mood swings
So, how is the baby doing this week?
Fetal Movements And Position During The 31st Week Of Pregnancy
The baby movements will be strong this week, but the frequency of movements might reduce to some extent. Since the baby is growing, the space inside the uterus is not enough for the baby to move freely.
Your OB/GYN Visit
During your prenatal visit this week, the doctor will:
- Advise a urine test to check the protein or sugar level
- Check your blood pressure
- Swelling of hands, feet and other parts of the body
- Measure the size of the womb
- Monitor the fetal heart rate
In case you have gestational diabetes, an ultrasound may be done to check the fetal position and the development of the baby.

You are likely to have the below tests:
- Fetal fibronectin (15): This test is performed to determine the possibility of a preterm. The cervical fluid is analyzed for a glycoprotein called fibronectin, which is found between the amniotic sac and the uterine lining. A positive test result can be an indication of preterm labor or any other complications. However, a negative result can avoid unnecessary hospitalization.
If the test results are normal and your doctor gives you a clean bill of health, all you need to do is follow a healthy diet and regimen for a smooth delivery.
Tips For Mom-to-be
- Drink plenty of water and stay hydrated.
- Stick to a healthy lifestyle and eat home cooked food. Include fish like pollock, salmon, shrimp, catfish, anchovies, and cod that are an excellent source of omega-3 fatty acids. Avoid shark, tilefish, king mackerel and swordfish as they contain high levels of mercury.
- Quit smoking, drinking alcohol and excess caffeine intake.
- Continue taking prenatal vitamin supplements like folic acid and iron.
- Engage in moderate physical activities like walking. You can also consider Pilates to strengthen your pelvic floor and back muscles.

- Do not take any medication without the doctor’s permission.
- Wear loose, breathable clothes.
