25 Weeks Pregnant

Length of baby: 34.2cm
Weight of baby: 680g (0.68kg)
At week 25, your baby is improving it’s dexterity in the hands and fingers, which means it will be able to open and close the hands and even grab hold of the umbilical cord.


At this point, all you can do is reminisce the carefree days of pre-pregnancy. But on the plus side, you will get to see your little one soon and the carefree days that you miss would seem insignificant. 

Sleepless nights await you, together with a dosage of leg cramps and body aches. Make sure you take time to relax each day with your feet raised to alleviate the tiredness and swelling on your legs.

25 weeks pregnant is how many months? 25 weeks pregnant is six months and one week pregnant.



How big is baby at 25 weeks? Your baby is the size of a cauliflower which is about 34.2cm.

The current weight of your baby is about 680grams (0.68kg).



This is the weight gain that you must achieve this week.

Underweight(BMI <18.5)  0.44kg to 0.58kg
Normal weight(BMI 18.5 to 24.9)0.39kg to 0.50kg
Overweight(BMI 25 to 29.9) 0.23kg to 0.33kg
Obese(BMI ≥ 30) 0.16kg to 0.25kg

During the second trimester, you will need to eat an extra 340 calories a day.



Your ever growing belly will soon pose as a challenge to get comfortable falling asleep. You will soon feel weighed down by your ever increasing belly size.

Being 25 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • More luscious hair. Thanks to your hormones, your hair will be more lustrous than usual. You will also find yourself shedding less hair. Enjoy it while it lasts.
  • Constipation. Your body produces the hormone, progesterone, during this period, which relaxes the muscles in your digestive track and causes food to pass through slower than usual. On top of that, the baby in your ever expanding uterus is putting pressure on your rectum. These in turn causes constipation. Remember to take lots of high fibre foods and drink lots of water to counter this problem.
  • Bloating. As digestion is slowed due to the hormone progesterone, this creates excess gas in your stomach.
  • Piles (Hemorrhoids). With a combination of constipation and the baby pressing against your digestive track, you might find yourself developing piles.
  • Trouble moving about. Because of your growing belly, you will find yourself having trouble getting about. Do be careful and stop to rest if you are feeling dizzy or tired.


During this period, your body produces the hormone progesterone which relaxes the muscles in your digestive track and causes food to pass through slower than usual. This causes constipation, so remember to take lots of high fibre foods and drink lots of water.



The movements in your belly are starting to become more obvious. Regular movements from your baby is a good and healthy sign.

If you haven’t felt the baby for some time and want some reassurance, a tip is to drink some ice water or play some music to get your baby moving.

At this stage you would have gained anywhere between 6.8kg and 8.2kg. You might be starting to feel the weight gain, and might start to be self-conscious. But remember! The extra weight is good for you and your baby needs it!

Also take note that there will be some fluctuations in the weight gain each week, so it is more important to keep in mind the total weight gain that you should achieve. If weight gain is a problem, do inform your Doctor.

Remember to eat plenty of nutritional foods including green leafy vegetables and avoid foods that have nutritionally empty calories.

You may also have your glucose screening test sometime between week 25 to week 28. This test can rule out gestational diabetes and can alert your doctor if something is wrong.



Your baby is now understanding equilibrium, learning the difference between up and down.

The previously lean looking foetus is now starting to go away as your baby is putting on more baby fats. The little one is gaining weight and getting stronger, and the wrinkled skin is now smoothening out.

Sweat glands will develop in the skin, together with capillaries, which are also forming under the skin. Blood vessels are developing in the lungs to ready the little one to breath independently, once it is out of the womb.

Your baby will also be improving the dexterity in the hands and fingers, which means he or she will be able to open and close the hands and even grab hold of the umbilical cord.



Reminders for the week:

  • Go for a final trip before you are too “big”
  • Go for a birth education class
