For newly pregnant women, there may be persistent breast swelling and pain, as well as drowsiness, fatigue, or generalized fever, but the specific performance varies from person to person. After pregnancy, the estrogen and progesterone in the body will continue to be at a high level, so the high level of estrogen and progesterone will stimulate the development of mammary glands and alveoli, resulting in obvious breast swelling and pain, and may also cause nipple erection, as well as nipple and areola deepening of the local color. Due to the influence of hormones in the body, it may also lead to obvious drowsiness, fatigue, and even dizziness in the early stage of pregnancy. At this time, the gastrointestinal tract peristalsis is relatively fast, so there will also be an obvious increase in appetite as well as the obvious feeling of hunger, but with the prolongation of menopause, it may lead to gastrointestinal tract peristalsis slowed down and cause constipation, and may even cause nausea and vomiting of early pregnancy reaction. At the same time, because the progesterone has been in a high level of state, so it will often lead to the body’s basal body temperature rises significantly, and cause a woman to have a generalized fever symptoms, but this time there will be no fever and other abnormal phenomena. Since everyone’s body is different, the specific symptoms of pregnancy vary from person to person, and not every woman will experience the above symptoms.
