What are the signs of pregnancy? Mothers who want to have children, be aware that pregnancy is not without warning, if you observe the small changes in your body carefully enough:

• Amenorrhea: Healthy women of childbearing age, the menstrual cycle has been very regular, There is a history of sexual intercourse and no reliable contraceptive measures. There are no sudden changes in the living environment, violent emotional fluctuations, and overwork.
• Nausea and vomiting: About 40 days after menopause, most pregnant women will experience nausea and vomiting, especially in the morning on an empty stomach, with symptoms such as loss of appetite and indigestion. Special preference for a certain food, such as liking sour (preserved apricot), spicy food, etc.
• Fatigue and lethargy: During pregnancy, despite being healthy, you always feel tired, lethargic, or have no interest in doing things.
• Breast changes: At this time, the breasts are swollen, painful, and gradually enlarged, the nipples feel tingling, the areolas become larger and begin to color (intensify), and the veins under the breasts can be seen dilated.
• Frequency urination: First, because the maternal metabolites increase after pregnancy, and the infant metabolites are also excreted by the mother, thus greatly increasing the workload of the kidneys and increasing the amount of urine. Second, because the enlarged uterus or fetal head descends to compress the bladder, the capacity of the bladder is reduced, and the frequency of urination is increased. If it is just excessive urination and frequent urination, it is a normal phenomenon and does not require special treatment. The symptoms will naturally disappear after the baby is born.
• Elevated basal body temperature: Under normal circumstances, the basal body temperature curve increases by 0.3-0.5 degrees Celsius after ovulation, due to the action of progesterone, until it begins to decrease 1-12 days before menstruation or on the first day of menstruation . If the basal body temperature rises and the menstrual period expires, the basal body temperature will not drop continuously. For example, for as long as 16 days, the possibility of conception is high. However, other factors that can cause elevated body temperature, such as systemic infectious diseases, need to be excluded.

In daily life, you can start with the most natural food supplements, such as: animal liver and kidney, beans, fruits, dairy products, green leafy vegetables (spinach, lettuce, asparagus, rapeseed) are rich in folic acid, and it is recommended to take them regularly.

Mothers may experience bleeding in the early stages of pregnancy, which is caused by the immature placenta and insufficient secretion of hormones. At this point should rest in bed.

Like continuous swimming, stationary bike riding, walking, and moderate aerobic exercise, but it's best to discuss with your obstetrician before any activity, and choose an activity that suits your situation.

If a pregnant woman experiences bleeding after sexual intercourse, she should seek an obstetrician immediately for examination.
