Symptoms you may experience at 31 weeks pregnant

As you reach the 31st week of your pregnancy, you may notice some new and continuing symptoms. These may include the following:

  • Tiredness
  • Shortness of Breath
  • Heartburn
  • breathlessness.
  • Frequent urination.
  • Leaky breasts.
  • Leg cramps and/or back pain.
  • Hemorrhoids.
  • Constipation.


You may feel more tired than usual as your body works harder to support your growing baby. Be sure to get plenty of rest and drink plenty of fluids.

Shortness of breath:

You may find it harder to breathe as your uterus pressure your lungs. This is normal and should improve after delivery.


Many women experience heartburn during pregnancy, often due to the increased production of progesterone.


This is normal due to the pregnancy hormone progesterone, which relaxes smooth muscle tissue throughout your body, including your bronchial tubes. Unfortunately, this can make breathing more difficult.

Frequent urination:

As your baby grows, they will pressure your bladder, causing you to feel the need to urinate more often.

Leaky breasts:

Many women experience a discharge from their breasts called colostrum in the final weeks of pregnancy. Colostrum is the precursor to breast milk and is thin and watery. Therefore, it is usual that your breasts leak colostrum even if you are not breastfeeding. (If so, try tucking some nursing pads into your bra to protect your clothes.)

Leg cramps and/or back pain:

These are common complaints during pregnancy and can be caused by several things, such as the weight of your uterus, edema, or constipation.


Hemorrhoids are swollen veins in your rectum and anus that may become inflamed and itchy during pregnancy. Unfortunately, there is not much you can do to prevent them, but using a hemorrhoid cream or suppository may help relieve symptoms.


Constipation is also common during pregnancy and can be caused by several things, such as the increased production of progesterone (pregnancy hormones), which relaxes smooth muscle tissue throughout your body, including your bowels. You may find relief from constipation by drinking plenty of fluids, eating high-fiber foods, and exercising regularly.

You can ameliorate your symptoms with pregnancy affirmations, birth affirmations, and hypnobirthing affirmations.

31 Weeks Fetus

31 weeks into development, the fetus is approximately 16 to 17 inches long and weighs around 4 pounds. At this stage in pregnancy, the mother may begin to feel Braxton Hicks contractions, which are irregular and brief contractions of the uterus that can last anywhere from a few seconds to a few minutes. These contractions are normal and help the mother’s body to prepare for labor. The baby’s lungs continue to develop and mature, and the digestive system begins to function.

The 31-week-old fetus grows rapidly and will continue to do so until birth. Although the 31-week fetus is still considered premature, with proper medical care, most babies born at this gestational age survive and go on to lead healthy lives.

31 Weeks Belly

Pregnancy is a fantastic time for a woman’s body. Over nine months, the body undergoes tremendous changes to accommodate a growing baby. One of the most noticeable changes is the expansion of the belly. For many women, this can be a source of pride and satisfaction, as it is a physical representation of the life they are creating. However, for some women, the 31 weeks belly can be a source of anxiety and insecurity.

There is no right or wrong way to feel about a 31 weeks belly. Some women love how their bodies look and feel during pregnancy, while others may feel self-conscious or uncomfortable. The important thing is to listen to your own body and do what feels right for you. If you’re unhappy with your 31 weeks belly, there are things you can do to help improve your self-image and confidence.

Talk to your doctor or a therapist about your feelings, wear clothes that make you feel good, and focus on the positive aspects of pregnancy. Remember that your 31 weeks belly is only temporary and that you will soon be holding your beautiful new baby in your arms.
