Signs of pregnancy at week 7

They become obvious, because hormonal changes are already actively taking place in a woman’s body:

  1. Increasingly, appetite changes, salivation worries. If before you ate with great reluctance, now you often snack and look forward to each meal. Certain foods and odors cause nausea, but vomiting is generally only seen in the morning. Some women begin to suffer from early toxicosis, this is evidenced by poor health, frequent vomiting and weight loss.
  2. The emotional state of a woman is very complex and contradictory.… She is glad, but she is constantly worried about something. This period is especially difficult for mothers who are expecting their first child. This becomes the reason for excessive suspiciousness, irritability, tearfulness and changeable mood. The early stages are characterized by lethargy, weakness and dizziness. All this makes a woman worry about her health, and sometimes is the cause of hypochondria.
  3. At the seventh week, the formation of the 1st wave of placentation begins. Chorion gradually transforms into placenta, later forming the uteroplacental complex… This process is accompanied by an increase in the concentration of chorionic gonadotropin in the urine and blood of a woman. Now about the normal course of pregnancy with an increase in the amount of hCG.
  4. The uterus has grown to a goose egg, which can be easily determined during a gynecological examination. And when conducting an ultrasound in the uterus, the embryo is clearly identified, you can consider its shape and measure the length.
