Feelings of a mother in the 5th week

This week brings a whole range of new sensations to a woman, but not all of them can be pleasant.

Emotions and behavior

In the emotional sphere, the first changes are observed. In addition to anxiety about the onset of pregnancy and anxiety for the unborn child, one can also note increased anxiety and emotionality, which will accompany a woman throughout the entire period of waiting for the baby. Changes in behavior are associated with changes in hormonal levels and with the beginning of the restructuring of the body.


At 5 weeks, the woman begins to experience slight discomfort. From the usual rhythm of life, fatigue sets in faster. In the morning, ailments are common – headache, nausea, and even vomiting. In general, in the first trimester, nausea can be provoked by anything: the taste of previously favorite foods and products, strong or strong odors, and sometimes even the sight of certain dishes or thoughts about them. In order to cope with nausea, a woman can temporarily stop cooking herself. Let someone close to you take on this responsibility: husband, mother or grandmother. This will help you get through the first trimester more easily.

Intimate life

For a period of 5 weeks, if all is well, there are no contraindications for intimacy… However, any uncharacteristic discharge, pain or pulling sensation in the lower abdomen should be a signal to refuse intimacy and immediately seek medical attention. It is the early dates that are dangerous times for spontaneous interruption.

  • The woman’s breasts begin to become sensitive;
  • Now it is necessary to more carefully choose a position for sleeping and for sex;
  • Touching the chest, and especially the nipples, is sometimes painful and unpleasant.

In order to avoid embarrassing situations, tell your man about these changes in your body.

What happens in the mother’s body in the 5th week?

This is the very period when the expectant mother learns about her new status. If the news brings positive emotions to the woman, then this has the best effect on the development of the baby.

HCG level

The first hormonal changes occur in the woman’s body: the corpus luteum of the ovary continues to produce estrogenic compounds and progesterone, due to which pregnancy is supported and which contribute to the cessation of ovulation. The fetal membrane secretes chorionic gonadotropin – This is a specific hormone that is produced in a woman’s body only during the period of bearing a child, and it is on its definition that home express pregnancy tests are based, as well as laboratory tests to determine pregnancy.

Ectopic pregnancy

If there is the slightest danger or suspicion of an ectopic pregnancy, the gynecologist should prescribe a blood test for hCG. Such an analysis makes it possible to conclude with confidence whether the fetus is developing in the uterus or whether it is fixed in the fallopian tube. In the normal course of pregnancy, the hCG content in a woman’s blood doubles daily., with an ectopic – the level of its content is reduced.

Decreased levels of hCG – a reason for the appointment of a more serious examination, but not a reason for panic. A woman needs to remember how important her positive emotional attitude is for her unborn child.

Fetal development in the 5th week
