It is in the fifth week of pregnancy that most women think about its onset due to the absence of another menstruation. A home pregnancy test should probably already show a positive result.
Early pregnancy signs may include drowsiness, headaches, decreased appetite, a slight increase in body temperature, frequent urge to urinate, nausea and vomiting caused by early toxicosis of pregnant women. Various unexpected tastes may appear for sweet or salty foods. The cause of early toxicosis is hormonal changes in the body of a pregnant woman.

He will retreat after about 12 weeks. If nausea and headaches in the fifth week of pregnancy cause inconvenience to a woman, then you should see a doctor.
