25 weeks pregnantPin

When you are 25 weeks pregnant, your baby is drinking the amniotic fluid, which is actually quite healthy and contains carbohydrates, salt, proteins, and lipids for example.

Your uterus is now the size of a soccer ball. How about your hubby, is he gaining a small baby belly as well? Learn about the most common sympathy pregnancy symptoms in men here.

Your Baby’s Development

Fetal Age and Size

25 weeks ultrasoundPinThe fetal age of your baby is now 23 weeks and you are entering the 7th month of pregnancy. Kind of cool, don’t you think!?

Your baby now measures about 13.5 inches (34 cm) from head to heels. The weight would be around 1.5 Pounds (680gr).

Your baby is slowly starting to store fat and will, therefore, be a little bit chubbier. His or her proportions are now quite much like a newborn baby, although, of course much smaller and more skinny.

Fetal Development in Week 25

This is a busy week for your baby’s physical development.

The spinal structures begin to form a total of  33 rings, 150 joints, and 1000 ligaments.

Your baby’s lungs are developing rapidly this week. In particular, the lower airways of the lungs are developing.

Although at this time, lung surfactants, which aid in lung expansion after the birth of the baby, are already present, the lungs are still very immature to function properly like sending out oxygen to the bloodstream during inhalation and releasing carbon dioxide during exhalation.

During the later part of the week, blood vessels are starting to develop in the lungs- that’s closer to the full maturity of the lungs.

Aside from lung developments, your baby’s nostrils begin to open, though they are still plugged up with amniotic fluid.

The skin of your baby is now smoother than before. It is because the capillaries, which are small vessels filled with blood, are now beginning to develop under the skin. The building up of fat also helps.

Hair growth is also taking place at this time.

Your Baby’s Senses in Pregnancy Week 25

Even though your baby’s eyelids are still closed, he or she can see the difference between dark and light.

The baby’s hearing is also improving and babies can learn to recognize the voice of their mom and dad.

Your baby’s sense of balance is also starting to develop. They know which way is up or down inside your womb.

Your Belly & Weight

Your uterus is the size of a soccer ball.

It is quite individual how much and how quickly we gain weight during pregnancy, but on average, a mom would have increased some 14 lbs (7 kg) so far. Read more about pregnancy weight gain here.

Because of your growing uterus, it can place pressure on your back as well as on your pelvis. This is the reason why you might experience periodic shooting pains in areas like your lower back and legs.

If you experience this, you have to take a rest, a warm bath, or you can apply a cold compress to the area. You can also try using a maternity support belt, like this one, which provides good help for some pregnant women.

Pregnancy Symptoms in Week 25


Common problems during this period are possible development of hemorrhoids, which are actually varicose veins. The size can be as small as a raisin or it can go as large as a grapefruit (OK, that’s not common, promise…).

Fifty percent of pregnant women experience hemorrhoids to some degree. It is due to the fact that the uterus is enlarging and there is an increase of blood flow to the pelvic area, which causes the veins of the rectal walls to swell.

Hemorrhoids are painful and itchy and can cause rectal bleeding. The best way to deal with them is to prevent constipation. Constipation can actually worsen the case. So you have to increase fiber in the diet and increase your fluid intake. (Read more about healthy eating during pregnancy here.)

If you do get hemorrhoids, a home remedy is to apply a cold compress to the affected area for more than one time in a day. This is done to aid in decreasing the swelling and discomfort. Soaking in warm water or having a hot sitz bath can also do the trick. If these won’t help at all, refer to your health care provider for some medical alternatives.

Activity Intolerance

Aside from hemorrhoids, you may also experience activity intolerance. This is because of the many changes in your circulatory system such as an increase in blood volume and an increase in cardiac workload. So whenever you feel tired and dizzy, you should take a lot of rest.

Heartburn & Snoring

As your baby continues to grow, he or she will put pressure on your digestive tract, which can push acid up your esophagus (heartburn). Painful and uncomfortable. A tip is to add a couple of extra pillows or raise the head-end of your bed a bit if this bothers you when trying to sleep.

An elevated head-ed can also prevent or mitigate the snoring that around a third of all pregnant women experience. The snoring is said to be due to the increased blood volume and/or the pregnancy hormones that cause the mucus membranes in your nose to swollen.

Restless legs syndrome

If it feels uncomfortable to hold your legs still, you might have restless legs syndrome. It can feel like tingling or “crawling” in the legs while resting. You can actually also get it in your arms. Uncomfortable!

It does disappear during the weeks after giving birth, but since that is quite a few weeks into the future, you can try other remedies, such as light exercise and avoiding caffeine.

Restless legs syndrome in pregnancy has also been associated with low iron levels, so make sure to ask your health care provider for a test.

Carpal tunnel syndrome

If your hands tend to tingle or feel numb, you might have carpal tunnel syndrome. This is due to a combination of hormonal changes, water retention, and increased blood volume that puts pressure on the nerve ends in the wrists.

It is temporary and usually, no treatment at all is needed.

Thicker hair

Most pregnancy symptoms are annoying, so let’s end this discussion with a positive symptom (for most moms) – thicker hair! The pregnancy hormones make you shed less hair.

When 25 weeks pregnant, it is time to start thinking about attending a prenatal birthing class. You can do it where you live or online (or both). I have added some good classes in the box below. Also, for more high-quality online prenatal classes, check my review here of a few classes that I have followed.
