The sixth month is the final month of the second trimester, and you are just a few months away from delivering your little one. By this time, your belly is protruded, and the glow is evident on your face. The baby is growing fast, and your body is undergoing many changes.

Momjunction helps you know about the bodily changes, the baby’s development, and the possible complications of pregnancy as well as the precautions to be taken this month.

What Are The Symptoms Of Pregnancy In The Sixth Month?

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 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, causing 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.
