Once you reach week 25 of your pregnancy, you’ll be nearing the end of your second trimester. It can feel like times flies! At 25 weeks pregnant, you’re approximately 5 months and 2 weeks along. Your baby has been growing steadily and even though it’s still not ready, it won’t be long before it comes into the world.

Week 25 of pregnancy comes with many changes, both for you and your baby. You can develop Restless Leg Syndrome (RLS), heartburn, Carpal Tunnel Syndrome, and other symptoms that might be uncomfortable but normal during this period.

Your 25-week old baby is constantly growing, moving, and getting ready to meet you. Read on to learn more about the changes in your and your baby’s bodies during week 25 of pregnancy.

Your baby at week 25 of pregnancy

By week 25 of pregnancy, your baby is starting to gain baby fat, which will smooth out its skin and make it look chubbier. If your baby has hair already, its color and texture might be starting to show. Your baby’s reflexes are also developing. 

Your 25-week old baby will enjoy jumping and playing inside your belly, and they’ll be able to hear your voice and other noises. Fingerprints have formed already, and palm creases are beginning to show.

Your baby is also looking more pink as small vessels in their skin called capillaries start to form, enhancing the blood flow under their skin. Although the baby’s eyelids are still closed, the cells that allow vision — called rods and cones — have formed and it can sense light and dark.

How big is your baby at 25 weeks pregnant?

By the time you’re 25 weeks pregnant, your baby will weigh approximately 1.7 pounds (785 grams) and measure 13.1 inches (33,6 cm). If we’re comparing baby sizes to fruits and vegetables, your baby is already the size of a full ear of corn. Along with other changes that are occurring in your baby’s body, this weight gain is already preparing them for life outside your belly.

25 weeks pregnant baby position

At this point the bab has not yet decided to assume the head down position in readiness for birth. The head is still near your chest and the feet face downwards. It will take up this position very soon though, sometimes as early as the following week.

Pregnancy week 25 fetal development

During week 25 of pregnancy, your baby’s nose and nostrils begin to function. During this week, your baby will start to breathe in amniotic fluid. The capillaries that are forming on your baby’s skin will also form inside his or her lungs, allowing the baby to take practice breaths from now on.

Your baby’s lungs have also started to produce surfactant, which will help them breathe after birth. However, their lungs are still immature and can’t oxygenate the baby’s blood.

A 25-week old baby is also starting to develop its sense of balance. They’ll be able to differentiate which way is up or down inside your uterus. They’re also becoming more dexterous, and they’ll be able to perform grasping motions. They can even grab their own umbilical cord!

Your body at week 25 of pregnancy

Your baby isn’t the only that’s changing during week 25 of pregnancy. During this week, you’ll probably see an increase in your weight, and you might experience new symptoms. Some symptoms of pregnancy can be uncomfortable, but remember that they’re a sign of all the things your body is doing to help your baby grow strong!

25 weeks pregnant belly

By week 25 of pregnancy, your uterus has reached the size of a soccer ball. You’ll have gained 15 to 18 lbs (7-8 kg) during your pregnancy, or 25 to 40 lbs (11- 18 kg) if you’re having twins. Many women start gaining more water weight around this time. As long as you’re gaining an adequate amount of weight, these fluctuations are normal.

You’ll notice that your baby’s movements get stronger and develop certain patterns. So be prepared for kicks, somersaults, and jumps! Your baby will also probably start reacting to music, voices, and sounds.

25 weeks pregnant symptoms

Many women start feeling more tired around the end of their second trimester. Your belly is getting bigger, so it makes sense if you feel weighed down. Some of the symptoms of week 25 of pregnancy include:

  • Restless Leg Syndrome: RSL symptoms make you feel the urge to move your legs constantly to relieve a tingling or crawling sensation.

This symptom appears when you’re resting or sleeping, and some women also feel it in their arms, thighs, or hands.

The cause of RSL hasn’t been identified, but the main mechanisms that may contribute to the development of RLS during pregnancy are hormonal changes, as well as iron and folate deficiencies. The good news is that it goes away about 4 weeks after childbirth.

RLS treatment during pregnancy includes mild exercise, warm baths before bed, taking supplements such as iron, folates, vitamin B12, magnesium, and avoiding caffeine — remember to consult your doctor before taking any medications. 

  • Thicker hair: the hormonal changes during your pregnancy inhibit normal hair loss. Enjoy this perk now, since all the hair you don’t lose during pregnancy will shed after the birth.
  • Carpal Tunnel Syndrome: hormonal fluctuations, fluid retention with a tendency to edema, nerve hypersensitivity, and glucose level fluctuations can cause the symptoms of carpal tunnel syndrome such as temporary numbness or tingling in your hands. Symptoms are usually mild and are not the matter of concern. Treatment is not required in most of the cases.
  • Hemorrhoids: your growing belly puts pressure on your pelvic veins, which can cause hemorrhoids. They’re uncomfortable, but they’re common during pregnancy and should disappear after delivery.
  • Heartburn or indigestion: the baby will also put pressure on your digestive tract, which can push acid up your esophagus.
  • Bloating: during pregnancy, hormonal changes will slow down your digestion. This can cause gas to accumulate, leading to abdominal bloating and constipation.

25 weeks pregnant ultrasound

You probably won’t have an ultrasound scheduled for week 25 of pregnancy, unless you’re under close monitoring from your doctor. You should be getting a glucose challenge screening test between weeks 24 to 28 to rule out gestational diabetes.

If you’ve already had the test and got abnormal results, your doctor could schedule a repeat test for this week.

25 weeks pregnant lifestyle

  • Keep up with your healthy diet: keep high-fiber diet, get plenty of vegetables, fruits, nuts and seeds, low-mercury fish, and lean protein. You shouldn’t try to eat for two, but it’ also recommended for you not to skip meals 
  • Mild exercise: avoid contact sports, lifting excessive weights, and lying on your back. But besides that, it’s fine to keep exercising regularly. Listen to your body (and your doctor!) and don’t work out when you’re feeling too tired, short of breath, or dizzy.
  • Drink lots of water: making sure you’re properly hydrated can help with constipation, bloating, and hemorrhoids.
  • Moisturize: you can develop stretch marks on your tummy and breasts around week 25 of pregnancy. You can also get itchy skin rashes. Moisturize daily to relieve these issues.

Sex at week 25 of pregnancy

Sex is safe throughout your pregnancy right up until your due date. In fact, many women find that their sex drive increases with pregnancy. By week 25 of pregnancy, some positions might make you uncomfortable, so you and your partner can try finding new positions that work for you.

It’s also perfectly safe to masturbate during pregnancy. And hey, there are many beneficial masturbation effects on women’s health. 

25 weeks pregnant checklist

  • Think about your birth plan: births don’t always go according to, well, birth plans. But this is a good time to start thinking about the type of birth you’d like.
  • Plan for your baby: start buying your baby-items before your bump gets bigger and you feel more uncomfortable.
  • Spend time with your partner: during their second trimester, many women experience less nausea but can still move around comfortably. This might be the perfect moment to plan a trip or spend more time with your partner before the baby comes!
  • Learn more about newborn babies: especially if you’re a first-time mom, now is the time to start learning more about your newest addition, how to care for them, and what to expect.
  • Manage your stress: now that delivery isn’t too far away, it’s normal to feel worried and anxious. But studies have shown that women who negate positive feelings during pregnancy are more likely to suffer from postpartum depression, so week 25 of pregnancy is a great moment to learn some stress management techniques.

What to ask your doctor?

Even if you don’t have an appointment this week, talk to your doctor if you experience contractions, spotting, bleeding, or any symptoms that concern you. If you do have an antenatal appointment, discuss your symptoms and birth plan with your doctor. Your doctor or midwife can also advise you on how to manage symptoms during week 25 of pregnancy.

Week 25 of pregnancy is an exciting time! Your baby has been growing and getting ready to meet you, and many important changes are happening inside your belly. You’ll be entering your third trimester soon, which means it won’t be long until the baby arrives!
