Symptoms at 40 weeks of pregnancy

Your pregnancy is in the last few days, but it is still common for you to feel some discomfort, which will go away as soon as the baby is born. See what are the main symptoms of 40 weeks of pregnancy:


One of the main symptoms of 40 weeks of pregnancy is tiredness and the result of this is the mother’s exhaustion, which at this stage reaches its limit. It is normal that she can no longer sleep well, and not even walk or do basic daily tasks. Therefore, the best thing to do is to use this period to rest a lot and recharge your energy.


Swelling can also be quite evident during 40 weeks, especially in the legs, feet and hands. To avoid being too uncomfortable, always opt for comfortable clothes and shoes and, whenever possible, rest with your legs elevated.


Can’t wait to have your baby on your lap? The anxiety that pregnancy is more an expected symptom. What we can tell you is that the time is almost here and trying to stay calm is essential for the last few days to be of great health and well-being, both for you and your baby. Try activities that calm you down, have calming teas and relax! The special and unforgettable time is almost here.


If you haven’t felt them yet, chances are they start during 40 weeks of pregnancy. And as mentioned earlier, it is essential that you repair all the symptoms and keep an eye on the periodicity of the contractions, considering that the sign that most indicates that you are in active labor is when they start to happen at an interval of time equal to less than 10 in 10 minutes, being the ideal time to notify your doctor.

Back pains

This symptom has been following you for a few weeks now and yes, it will remain! The result of this is the weight of the belly that reflects directly on the back. So that this is not so uncomfortable and recurrent, try to stay as rested as possible and prioritize a regular night’s sleep.

frequent urination

In the 40 gestational weeks, you must have already gotten used to the extra trips to the bathroom, right? Well then… The increase in urinary frequency during pregnancy is explained by the fact that the bladder is pressed by the uterus, reducing its reservoir. But calm down: this will pass as soon as your baby is born.

Changes in pregnant women at 40 weeks of pregnancy

The main change in pregnant women during the 40 weeks of pregnancy is linked to the increase in contractions that tend to become more constant and intense.

If perhaps they are still sporadic, a good tip is to walk at a faster pace, for 1 hour a day, which can be in the early morning or late afternoon, as long as you avoid the hottest times of the day.

Remember to be aware of the symptoms you experience during these days to notify your doctor and if you notice any more intense changes, go immediately to the maternity ward so they can check if it is time for the baby to be born.

Development of the fetus at 40 weeks of pregnancy

With 40 weeks of pregnancy, which marks the end of 9 gestational months, the development of the fetus is already complete and it is ready to be born. See below some evidence from this period:

  • The baby’s skin is smooth, has folds of fat, and there may still be vernix;
  • The baby may have little or a lot of hair, but it is very likely that he will lose some hair during the first few months of life;
  • Your muscles and joints are strengthened;
  • The baby can already react to sound and movement and is even familiar with sounds, such as the voice of the mother and father;
  • The nervous system is already fully formed so that it can survive outside the uterus, however its cells will multiply during the child’s first year;
  • The respiratory system is already formed, and once the umbilical cord is cut, the baby will be able to breathe on his own.

What is the size of the fetus at 40 weeks of pregnancy?

At 40 weeks of gestation, the fetus measures approximately 50cm, size equivalent to a pumpkin, and its estimated weight is 3.5 kilos.

Shave or not for childbirth: that’s the question!

This is a subject that usually generates many doubts among mothers and the answer is that there is no need to shave, as it is not prohibited: the hair has no influence at the time of childbirth, whether normal or cesarean. That is, it is at the woman’s discretion.

However, if you opt for waxing, it is important to take some precautions to make sure that the procedure will not cause any harm to the birth, such as a scratch, cut or ingrown hair that can inflame or become infected.

So avoid shaving too close to the birth date and, if possible, be very careful during the procedure. Other than that, you can continue with the process normally, either through blades or waxes.
