If you are 6 months pregnant, you are in the final month of your second trimester and only three months away from giving birth to your baby. Your belly has enlarged by this month, and you have a clear pregnancy radiance on your face. Your baby is growing quickly, and so is your body is changing dramatically.

This post informs you about the various changes in your body at six months of gestation, the baby’s development, and potential pregnancy complications, as well as the precautions you should take during this month.

What Are The Symptoms Of Pregnancy In The Sixth Month?

Dr. Alan Lindemann, MD, a former clinical associate professor at the University of North Dakota, says, “At six months of gestation, you would be approximately two-thirds through your pregnancy. Your baby has a reasonable chance of surviving in good condition. Twenty-five years ago, I delivered quadruplets at about that gestational age. All four babies weighed 1.5 pounds, give or take a few ounces. They all did well and have now reached healthy adulthood.”

The pregnancy symptoms that you may experience are (1) (2) (3):

  • Weight gain: You may gain 3 to 4 pounds by this month (4).
  • Fatigue: The body is working more for nourishing your baby, which makes you feel tired, although not as much as before.
  • Constipation: The pregnancy hormones relax the intestinal muscles. Also, the pressure of the growing uterus on the intestine slows the movement of food, leading to constipation.
  • Heartburn: The gastrointestinal tract relaxes due to the increased progesterone levels. The upward pressure that the uterus exerts on the stomach pushes the gastric juices into the esophagus, causing a burning sensation.
  • Flatulence (gas): As the progesterone hormone relaxes the intestinal muscles, the digestion process slows down and builds up gas.
  • Nasal congestion: An increase in the estrogen hormone results in swelling of the nasal passage lining, making way for more mucus and causing congestion.
  • Nosebleeds: An increase in the blood circulation during pregnancy expands the small blood vessels in the nose. The pressure exerted on the blood vessels can lead to nosebleeds.

  • Bleeding gums: An increase in the blood flow and hormonal changes are the reason for swollen and bleeding gums during pregnancy.
  • Increased appetite: As the morning sickness is minimal by this month, there is an elevation in food cravings. Cravings are normal and a reasonable increase in food intake necessary to meet the demands of the growing baby.
  • Swollen ankles: The water retention in the body and the pressure put by the growing uterus on the veins, restricting the backflow of the blood, leads to edema or swollen ankles.
  • Achy feet: The edema, as well as the pregnancy weight gain, put additional pressure on the feet causing the feet to ache.
  • Varicose veins: The pressure exerted by the growing uterus on the inferior vena cava (the largest vein in the body that carries blood from legs to heart) restricts the blood flow, causing the veins near the legs to swell.
  • White vaginal discharge: The cervix and the vaginal walls soften during pregnancy causing white discharge, which in turn prevents any bacteria from traveling to the uterus through the vagina.
  • Breathlessness: The growing uterus puts pressure on the diaphragm, which may cause breathlessness.
  • Backache: The uterus also puts pressure on your lower back. Also, pregnancy results in the stretching of the joint ligaments in the pelvic and lower back area. Both these factors lead to a backache.
  • Insomnia: Frequent visits to the bathroom, backache, nasal congestion, etc. can deprive you of a good night’s sleep.
  • Braxton Hicks contractions: Some women may feel painless contractions, which is normal and a way to prepare the body for delivery.

Physical Changes In The Sixth Month

The physical changes that you may experience include:

  • Stretch marks: The growing uterus causes tiny tears in the skin tissues, causing stretch marks.
  • Linea nigra: The line running down from the belly button to the pubis becomes darker.
  • Skin pigmentation changes: Production of more hormones during pregnancy can lead to skin pigmentation, also known as melasma. It appears as darkened spots near the cheeks, neck, and the forehead.
  • Colostrum: The breast may start leaking a yellowish liquid called colostrum, which is the first breast milk that your baby will feed on immediately after delivery.

Emotional Changes In The Sixth Month

Here are a few emotional changes you might experience:

  • Pregnancy brain: The inability to concentrate (absent-mindedness) or forgetfulness is all attributed to the hormonal changes during pregnancy. It is sometimes also referred to as momnesia.

  • Mood swings and anxiety: These happen are due to the hormonal changes during pregnancy.

Baby Developments In The Sixth Month Of Pregnancy

Dr. Lindemann adds, “At six months, the baby has developed arms, hands with ten fingers, legs with feet and ten toes, and good reflexes. The baby has eyes and eyelids so she or he can see, ears to hear, lips, nose, tongue, neck, and a heart that works. However, the baby’s lungs don’t work very well.”

The weeks from 21-24 constitute the sixth month. During these weeks, your baby grows from the size of a carrot to as big as the ear of corn (5). The baby attains a human face by now.

Baby weight: 8 ounces to 1 pound

Baby’s CRL (crown-rump length): It is about 8-12in (20-30cm)

Your baby’s growth spurts during this month. Here is how your little one’s body is developing this month (3), (6) (2) (7).

Frequently Asked Questions

1. Can I have a 4D ultrasound in six months of pregnancy?

Yes, week 24 (sixth month) of pregnancy is a good time to have a 4D ultrasound. Ultrasound during this month may also give you a lovely image of your baby (15).

2. Can I have contractions at six months pregnant?

Some women feel contractions in their uterus during the sixth month. These are called Braxton-Hicks contractions. This painless squeezing is how the uterus prepares for labor and delivery. These contractions are normal and do not indicate labor (16).

3. How do babies develop in twin pregnancies at six months?

Dr. Lindemann opines, “There are different types of twin gestations based on the number of placentas and the existence of membranes between the twins. Without a separating membrane, the twins have problems getting their umbilical cords twisted. There are often discrepancies in size with one twin growing larger than the other twin, probably because it gets more nutrition.”

“However, most twins contain a membrane between babies so that cords can’t get mixed up and they have their own nutrition. When this happens, twins have a reasonable chance of growing normally and being born relatively at term, for example at 39 weeks.”

Your adorable baby bump is very noticeable when you are 6 months pregnant. As you are ready to step into the third trimester of pregnancy, you may start experiencing subtle changes in your body as your uterus continues to expand. You could also have skin and emotional changes, which may persist in the proceeding months. However, you should take good care of yourself for the next three months to have a smooth delivery. So, avoid stressing out, pamper yourself with delectable yet healthy foods and hang out with your friends and family to enjoy this phase.
