When does early pregnancy reaction begin?

It is normal to have pregnancy reactions after pregnancy, but we should pay attention to our understanding of pregnancy reactions. Generally, most women will begin to experience early pregnancy reactions after six weeks of pregnancy, and will also have symptoms such as dizziness, fatigue, drowsiness and loss of appetite.

1. Most women may experience dizziness, fatigue, drowsiness, increased salivation, loss of appetite, nausea and vomiting after 6 weeks of pregnancy. Vomiting often occurs in the early morning or on an empty stomach. Some pregnant women particularly like to eat acidic and cold foods. The above phenomena are called early pregnancy reactions, which usually disappear on their own around 12 weeks after pregnancy. A few people have more severe early pregnancy reactions and they last longer.

2. Increased urination frequency: After 8 weeks of pregnancy, there may be an increase in urination frequency, which is caused by the compression and stimulation of the bladder after the enlarged uterus. After 12 weeks of pregnancy, the uterus extends beyond the pelvic cavity, the bladder is no longer compressed and stimulated, and the symptom of frequent urination is relieved by itself.

3. Breast changes: After pregnancy, under the joint stimulation of estrogen and progesterone, the breasts gradually grow larger from the 8th week, the color of the nipples and areola deepens, and dark brown nodules appear around the nipples. After 12 weeks, a small amount of clear milk will be secreted. Fifth, changes in basal body temperature: Women who measure basal body temperature can know early pregnancy. The normal basal body temperature of women is a two-way curve, that is, it is lower before ovulation and rises after ovulation. If the menstruation does not come before the due date, the body temperature will not drop after the rise and will remain for more than 18 days, which means that the woman is pregnant.
