Feelings of a mother

Many women note:

  • The work of the gastrointestinal tract slows down, and as a result, heartburn appears;
  • Intestinal motility is impaired, and constipation begins;
  • Is developing anemia (anemia);
  • Due to the sharp increase in weight, an additional load appears and, as a result, there are back pain;
  • Edema and pain in the leg area (due to prolonged stay on the legs);
  • Dyspnea;
  • Bring discomfort itching and burning in the anus when using the toilet;
  • Periodically pulls the stomach (this often happens due to the increased activity of the baby);
  • Continue excretions from the genitals (milky, not very abundant with a subtle smell of sour milk);
  • Appears dry eye syndrome (vision deteriorates);

As for external changes, here they also take place:

  • The breasts become plump and continue to grow (prepare for feeding a newborn baby);
  • The belly continues to grow. Now it grows not only forward, but also sideways;
  • Stretch marks appear in the abdomen and mammary glands;
  • Expansion of the veins is noted, especially in the legs;

Changes in a woman’s body:

Week 25 is the beginning of the end of the second trimester, that is, all the most significant changes in the mother’s body have already occurred, but small changes are still taking place here:

  • The uterus grows to the size of a soccer ball;
  • The fundus of the uterus rises to a distance of 25-27 cm above the bosom;

Feedback from forums and social networks:

It’s time to find out what women feel, because, as you yourself understand, everyone has their own body and completely different tolerances:


Week 25, so much passed, and how much more to endure! The lower back hurts very badly, especially when I stand for a long time, but at least my husband does a massage before going to bed and it’s easier. More recently, I discovered that it hurts to go to the toilet, it burns everything right to tears. I heard that this often happens in pregnant women, but I can’t stand it anymore. See a doctor tomorrow!


I recovered by 5 kg, and the doctor scolds that a lot. I feel fine, the only thing that worries me is that the pressure rises!


I recovered a lot. At 25 weeks I weigh 13 kg more than before pregnancy. The back hurts, it is very difficult to sleep on the side, the thigh is numb, but most of all the weight and possible complications due to it during childbirth are worried.


I feel like a sick person, not a pregnant woman. My bones ache very much, my stomach and lower back stretch, I can’t stand for a long time, sit too. And on top of that, I began to suffer from constipation! But on the other hand, I won’t endure for long, and I will see my long-awaited son!


I am pregnant with my second child. In the first pregnancy, I gained 11 kg, and now it is 25 weeks and already 8 kg. We are waiting for the boy. The breast swells and grows, I have already changed my underwear! The belly is tremendous. Feeling like nothing, only constant heartburn, no matter what I eat – the same thing.

  • Wear compression stockings or tights (they do a great job at relieving discomfort)

  • To avoid edema, consume liquid no later than 20 minutes before meals; do not eat after 8 pm; limit your salt intake; boil cranberry or lemon juice, which has an excellent diuretic effect;
  • Sleep at least 9 hours a day;
