Signs of pregnancy at week 7

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

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.

Reviews of women from forums and groups


Today I am starting my seventh week of pregnancy. I feel great. I am very afraid of toxicosis, because I had the so-called effect of reverse peristalsis even before pregnancy;


I don’t have toxicosis, but my general condition is rather strange … Now everything is fine, then a strong weakness attacks, and sometimes even signs of depression appear. But I am fighting it courageously;


Pungent odors irritate, sometimes nauseous, but fortunately there are no mood swings;


The veins on the chest became visible, as if they were tied with a blue-green mesh. Nausea disturbs in the morning, and when I go out into the fresh air;


I have become very irritable, I am looking for any trifle. I also react strongly to different smells;


And for me this period went just fine, no toxicosis. I was just taking the session, so I didn’t notice any sudden changes in mood and irritability.
