Physical changes that occur during pregnancy - the first trimester

During the first three months of pregnancy (first trimester) your body undergoes many changes. While your body adapts to your growing face, you may experience nausea, fatigue, back pain, emotional changes and stress. These things are normal during pregnancy as your body changes.

Some pregnant women may not feel any of these elements of discomfort. You will not feel most of them as the pregnancy progresses.

If you have been pregnant before, at this task you may experience other elements of discomfort. Just as every woman is unique, so is every pregnancy.

As your body changes you may feel the need to make changes in your daily life as well. Here are some of the most common changes or symptoms that you may experience during the first trimester of pregnancy.


During pregnancy you may feel tired even if you slept well enough at night. Many women feel exhausted in the first trimester.

Don't worry, it's normal. It is the way your body tells you that you need more rest. Fatigue will pass with time and will be replaced by a feeling of well-being and fullness of energy.

When you feel tired, rest. Try to sleep for about 8 hours at night and sleep a little more during the day. If you feel stressed try to find a way to relax.

You may want to start sleeping on the left side if you find it more comfortable. This position is recommended when you stand with your body on the horizontal because it ensures a better blood circulation with oxygen and nutrients to the fetus.

If you somehow have increased blood pressure in pregnancy it is even more important to stay on the left side when lying down.

Nausea and vomiting

Named morning sickness, nausea and vomiting are common at the beginning of pregnancy. However, for many women it does not manifest only in the morning.

Although it leaves an impression that they will last forever, nausea and vomiting usually disappear after the first trimester. Try some of these tips:

  • Eat smaller meals frequently (6-8 smaller meals better than 3 large meals).
  • Avoid fatty, fried or spicy foods.
  • Try using starch products such as cereals, mussels, toast, etc. Keep some near the bed and eat them before you get out of bed in the morning and when you wake up at night. Keep a few with you permanently for when you are feeling nauseous.
  • Try drinking carbonated mineral water between meals.
  • Ask your doctor if you can stop taking prenatal vitamins for a while if they worsen your morning sickness.
  • Ask your doctor if you should be taking Vitamin B6 for severe nausea and vomiting that does not improve with the dietary changes mentioned above.
  • If vomiting is common, it is advisable to notify your doctor to take measures to prevent dehydration. When nausea and vomiting begin to disappear, try to resume a healthy, complete diet and take prenatal vitamins.
  • Frequent urination

    Frequent urination is common during pregnancy. At the beginning of pregnancy, the uterus that grows presses on the bladder. If you experience pain or burn when you urinate or if your urine has pus or blood, consult your doctor urgently. You may have a urinary tract infection that requires treatment.


    As the uterus begins to enlarge it is possible to notice that you are starting to constipate. To prevent constipation try to eat fresh or dried fruits, raw vegetables, whole grains or whole grain bread daily.

    Also, try to drink 8-10 glasses of water daily. Some of these glasses of water can be replaced with fruit or vegetable juices.

    Try to avoid caffeine drinks and related products (coffee, black, green tea, cola of all types and other carbonated soft drinks) which, besides other possible harmful effects, induce the loss of bodily fluids and aggravate constipation.

    Varicose veins and hemorrhoids

    During pregnancy, the pressure exerted on the large veins behind the uterus leads to slowing of the return of blood to the heart.

    This can cause varicose dilation of the veins of the lower and vaginal limbs and around the anus (hemorrhoids). You can prevent varicose veins during pregnancy by:

  • Avoiding the use of clothing items that will tighten the leg in certain areas (high socks with strong elastic, garters, etc.).
  • Stay with your legs raised as long as possible at home and at work.
  • Leg cramps

    At different times during pregnancy you may have cramps in the legs, legs or thighs. This is due to a change in calcium metabolism.

    One way to prevent the appearance of these cramps is to make sure that your diet brings enough calcium to the body through totally or partially skimmed milk and calcium rich foods.

    You can also take a certain amount of calcium with prenatal vitamins, but you may need a calcium supplement if calcium is not enough in your daily diet. Take these supplements only with the advice and consent of the doctor.

    You can ease the sensation generated by cramps by gently stretching the muscle at the time of cramp. Contraction (shortening) of the muscle can aggravate the cramp. Applying heat around the muscle can help it relax.

    Nasal bleeding, clogged nose, gingival bleeding

    These elements of discomfort are the result of hormonal effects on the tissues of the neck, mouth and nose. They usually have no major effects and may not even be observed.

    When you blow your nose it is possible to notice a small amount of blood in the eliminated secretion. Blow the nose gently and stop a possible slight bleeding by gently tightening the nose between the police and the index for a few minutes.

    Consult your doctor if you have frequent nasal bleeding or if the bleeding does not stop within minutes of nasal compression. Any nasal clogging you have during pregnancy should not be very intense and can be improved by supplementing the amount of water you drink or by using a cold humidifier in the bedroom.

    Consult your doctor before self-administering large quantities of cold or clogged nose medication. To prevent gingival bleeding, reduced toothbrushes are indicated as intensity and duration using soft toothbrushes.
