How Many Months Pregnant Are You At 25 Weeks?

At 25 weeks, you are about five months and two weeks pregnant. You are in the second trimester of your pregnancy. By now, your baby starts to move frequently and may respond to touch or sound.

Here, we tell you more about the baby’s development in this week and how your body changes accordingly.

How Big Is Your Baby At 25 Weeks?

At 25 weeks, the baby is as big as a rutabaga (1). Your baby measures 13.6in (34.6cm) in length and weighs 1.46lb (660g) (2).

Baby Development At 25 Weeks

Here is how the organs are developing in this week:

Body parts Developmental stage
Skin Fat is depositing under the skin layer
Nose (3) Nostrils begin to open up
Reflexes (4) The baby can respond to sound, touch, and light
Spine Developing different parts
Lungs (5) Breathing patterns are developed. It occurs 44 times/ minute. The alveoli start creating surfactant (6)
Kidneys Start producing urine
Brain (7) Developing
Digestive system Still developing

The baby moves vigorously at this time and follows a sleep pattern, which indicates that the baby is healthy and doing fine inside the womb. The fetus is small and has plenty of space inside the uterus to move around, and can attain different birthing positions before coming into the optimal position.

The changes in this week may make you a little more uncomfortable than before. Read more about it next.

What Symptoms Of Pregnancy Do You Experience In The 25th Week?

The common symptoms in this week include:

  1. Weight gain: The weight gain should be based on the BMI (8):
BMI Below 18.5 18.5 – 24.9 25 – 29.9 30 and Above
Weight gain (Pounds) 28-40 25-35 15-25 11-20
  1. Trouble sleeping: Besides the bodily discomforts, frequent breaks to the bathroom during the night can disturb the sleep.
  1. Frequent urination: The pressure exerted by the growing uterus on the bladder increases the urge to urinate.
  1. Constipation: Progesterone relaxes the muscles of the digestive tract, which slows down the digestion process causing constipation.
  1. Hemorrhoids: Increased blood flow and constipation cause the veins in the rectal area to swell.
  1. Gas and bloating: Indigestion generates gas and makes you feel bloated.
  1. Heartburn: The growing uterus puts pressure on the stomach, which pushes the gastric acids up into the esophagus, causing heartburn.
  1. Back pain: The pressure exerted by the extra weight of the baby on the lower back can cause aches in the region.

  1. Fatigue: Since the body is working harder to nurture the baby, you’ll feel tired than usual.
  1. Edema: The water retention in the body causes swelling of hands and feet.
  1. Braxton Hicks contractions: You may experience irregular and less painful contractions that go away when you switch positions. The contractions are the body’s way of preparing for labor and delivery.
  1. Carpal tunnel syndrome: A tingling effect is felt in the hands and wrist, due to the increased blood volume that exerts pressure on the nerves.
  1. Snoring: An increase in the blood flow to the mucous membranes can cause nasal congestion and make you snore.
  1. Symphysis pubis dysfunction (SPD): This is a condition where the ligaments and the muscles of the pelvic joints are stretched, causing pain in the pelvic area. Pelvic tilts and kegel exercises help strengthen the muscles of pelvic area (9).
  1. Restless leg syndrome (RLS): Also known as Willis-Ekbom Disease, this condition causes a tingling effect in the legs along with an uncontrollable urge to move them. A low ferritin level in the blood (hemoglobin <11 g/dl), low folate, history of RLS before conception, RLS during the previous pregnancy are a few common reasons for this syndrome (10).

When To Call The Doctor

In the case of any of the following symptoms, call your doctor right away (11):

  • You experience contractions once in every 10 minutes or more, often within one hour (five or more contractions in an hour)
  • Fluid leak from your vagina (rupture of the amniotic sac)
  • Menstrual-like cramps
  • Low, dull backache
  • Pelvic pressure
  • Abdominal cramps with or without diarrhea
  • Vaginal bleeding

Even if the symptoms are normal, make sure you meet the doctor during the regular OB/GYN visit.

Your OB/GYN Visit

Here is what you can expect during your OB/GYN visit:

  • Weight check
  • Blood pressure
  • Glucose tolerance test: If the glucose challenge test results are abnormal, the doctor would suggest the glucose tolerance test to measure the sugar level in the mother’s bloodstream.

For the glucose challenge test, blood is drawn an hour after you drink glucose water, and is checked for increased blood sugar levels. In case of a positive test result, a glucose tolerance test will be done. This requires overnight fasting and blood will be drawn before you break the fast and is tested for sugar levels.

This is followed by an hourly blood test for the next three hours. An abnormal test result is an indication of gestational diabetes (12).

The doctor would recommend a healthy, low-sugar diet to keep gestational diabetes, if you have it, in control. Otherwise, you can follow a healthy diet and lifestyle to keep yourself and your baby healthy.
