At 8 months or 29 to 32 weeks pregnant, you are only a few weeks away from bringing your baby into the world (1). Now that you have seen your fully developed baby on the monitor during an ultrasound scan, you may be excited about seeing your baby soon. However, since you are close to going into labor, you should take specific precautions to ensure your and the baby’s safety and health.

This post explains the physical and emotional changes you will go through during the eighth month of your gestation; your baby’s growth, position, and movements; the diet to follow; and other measures you should take in this period.

Symptoms You Experience In The Eighth Month Of Pregnancy

Here are the symptoms you may experience this month (1), (2), (3):

  • Weight gain: It should increase as per your BMI (4)
Pregnancy monthBMI < 25BMI 25 – 30BMI > 30
8th8-9 kg5-6kg4-5kg
  • Breathlessness: The pressure put by the growing uterus on the diaphragm makes breathing difficult.
  • Tiredness: The body has to work more to meet the demands of the growing fetus, which causes fatigue.
  • Nasal congestion: Nasal membranes expand as the estrogen levels increase and cause more mucus to pass through, resulting in nasal congestion.
  • Heartburn: The growing uterus pushes the stomach upward, causing the gastric acids to go into the esophagus and triggering a burning sensation.
  • Bloating: The process of digestion is slowed down due to an increase in the progesterone levels. It makes the tummy gassier and leaves you bloated.
  • Constipation: As the digestion process slows down, the food tends to stay longer in the intestine, leading to constipation.
  • Braxton Hicks contraction: These are painless contractions felt in the lower abdomen. They are normal after the 34rd week of gestation and prepare the body for labor.
  • Hemorrhoids: The pressure exerted by the growing uterus on the inferior vena cava (largest vein in the body) restricts the blood flow, causing stasis of the blood in the veins. This results in the expansion of the blood vessels near the anal region, which can be painful and itchy.
  • Varicose veins: The pressure put on the inferior vena cava due to the expanding uterus restricts the backflow of the blood through the veins near the legs. It causes swelling of the blood vessels, also called varicose veins.
  • Edema: The water retention in the body causes swelling of the ankles and feet.
  • Backache: The growing uterus exerts pressure on the lower back, causing pain.
  • Insomnia: Frequent trips to the bathroom and the physical discomforts deprive you of a sound sleep.
  • Leg cramps: The extra weight, vitamin deficiency, or being too active or inactive are likely to cause leg cramps (5).
  • Increased vaginal discharge: The cervical wall and the vaginal wall soften during pregnancy, causing white discharge. It helps prevent any bacteria from traveling to the uterus through the birthing canal (6).
  • Abdominal pressure: The baby drops down into the pelvis by this month, due to which there will be extra pressure in the lower abdomen.

Physical Changes In The Eighth Month

By now, you may have experienced several physical changes due to the pregnancy. Here are some more that might become prominent this month.

  • The 8-month pregnant belly is more prominent and leans slightly downward as the baby moves to the head-down position by this time.
  • Hair fall reduces due to the hormonal changes, which makes your hair look fuller.
  • The breast starts leaking a yellow fluid called colostrum, which is the first milk your baby will feed.
  • The hormonal changes cause pigmentation that results in darker nipples and areola.
  • The growing uterus causes tearing of the skin tissues causing stretch marks.
  • The line between the belly button and the pubic hairline, referred to as the linea nigra, becomes darker due to pigmentation.

Emotional Changes In The Eighth Month

Emotional changes that could take a toll on you this month include:

  • Mood swings and anxiety
  • Stress as you may be worried about the delivery and the upcoming responsibilities

As you experience these changes, the baby continues to develop and get ready to come into the world soon.

Baby Development In The Eighth Month Of Pregnancy

By this time, your baby grows from the size of a butternut squash to a jicama (7).

  • Baby weight (8): 2.54 – 3.75lb (1.153 – 1.702kg)
  • Baby’s CRL (crown-rump length): 15.19 – 16.6in (38.6 – 42cm)

Here is how your baby is developing this month (2), (9), (10), (11):

Body partsDevelopment
LanugoBegins to fall off.
EyesStarts to open and close.
LungsNot fully matured, but breathing practices start.
BonesFully formed but are soft.
SkinLess wrinkled
NailsThey extend till the fingertips and toe tips.
Digestive systemStill developing
EarCan hear sounds, prefers mother’s voice or female voices to other voices
Nervous systemIt is almost developed and starts controlling the body functions.

As you are closer to the delivery date, this is also the ideal time to learn about all the possible positions that your baby can or will attain.

Baby’s Position And Movements In The Eighth Month

Position: By this month, the baby attains a head-down position, which is the ideal position for labor. It helps the baby’s head to properly fit into the pelvis for a smooth movement through the birthing canal during delivery.

However, the baby might sometimes attain the bottom-down position, which is also called breech presentation. But, there is nothing to worry about because your baby still has enough time to flip the position and get back to the ideal one just in time.

Movement: As the baby has grown bigger, there is not much space left inside the womb for free movements. Therefore, you may feel a decrease in the frequency of movements. Also, the kicks are not as stronger as they used to be earlier.

A healthy pregnancy is possible with a healthy lifestyle and diet. Next, we give you a list of dos and don’ts for this month.

Pregnancy Diet For The Eighth Month

Here is the list of foods that you must add to your diet (12):

  • Calcium promotes healthy bones and teeth in your baby. According to the American College of Obstetricians and Gynecologists (ACOG), a pregnant woman should take 1000mg of calcium/day. Add a lot of green leafy vegetables, bread, milk, and fortified cereals to your diet.
  • The ACOG recommends a daily intake of 600mcg folic acid for pregnant women. It is necessary for preventing birth defects of the brain and spine in the baby. Leafy vegetables (spinach, broccoli, romaine lettuce, and kale), kidney beans, lentils, nuts, citrus fruits, and beans are rich sources of folic acid.
  • Iron is necessary for the production of red blood cells that carry oxygen throughout the body. The recommended intake is 27 mg/day (including the supplement). Whole grain products, green leafy vegetables, dried fruit, beans, lean pork and beef, and sardines are a good source of iron.
  • Orange or yellow vegetables (sweet potatoes or carrots), leafy vegetables, liver, and milk are a rich source of vitamin A. The ACOG-recommended daily intake of this vitamin is 770mcg for promoting bone strength and healthy eyesight.
  • Salmon and milk are a good source of vitamin D that promotes healthy eyesight and strengthens the bones and teeth. According to the ACOG, the recommended intake is 600IU per day.
  • Protein is necessary for muscles and brain. It can be obtained from lean meat and poultry, eggs, seafood, peas, soy products, beans, milk, and unsalted seeds and nuts.
  • Vitamin C promotes healthy gums, teeth, and bones. Add citrus fruits, strawberries, tomatoes, and broccoli to your diet. The average daily recommended intake is 85mg.

Foods To Avoid During The Eighth Month

Here is the list of foods you need to avoid:

  • Avoid eating raw or uncooked food. It can cause listeriosis, a foodborne disease caused by bacteria (13).
  • Avoid taking too much caffeine, i.e., more than 200-300 mg/day (14).
  • Avoid eating swordfish, tilefish, king mackerel, and shark as they contain a high level of mercury.
  • Avoid unpasteurized milk and cheese.
  • Avoid deeply fried and spicy foods as they can aggravate heartburn, bloating and constipation.

Considering that you’re so close to labor, make sure you do not miss the gynecologist appointment this month.

What To Expect During Your Visit To Ob/Gyn?

Here are some of the tests that will be performed when you visit the doctor:

Physical examinations:
