1.Do you know how to calculate the due date? To calculate the due date, simply add 9 months and 1 week (280 days) to the first day of the last menstrual period. For example, if your last period is January 1, add 9 months to October 1 and 1 week (7 days) to October 8. October 8 is the expected date of delivery. The actual delivery may occur within 2 weeks before or after the due date. If your menstrual cycle is irregular or you cannot remember the date of your last menstrual period, please estimate it in early pregnancy based on gynecological examination or ultrasound. 2.What are the symptoms of pre-eclampsia miscarriage in early pregnancy? The symptoms of pre-eclampsia usually appear in the early stage of pregnancy (within 3 months), including: a small amount of vaginal bleeding, which may be accompanied by lower abdominal pain, but no tissue discharge. The symptoms are as follows: (1) Vaginal bleeding: The first symptom of preterm miscarriage is often vaginal bleeding. (2) Abdominal pain: often accompanied by vaginal bleeding, the pain may be mild or severe and may be accompanied by colic or constant pain. (3) No fetal heartbeat or uterus stops growing: Pregnant women should have regular maternity checkups. If you do not hear your baby’s heartbeat during the checkup, or if your uterus does not grow at the rate it should, you may be having a miscarriage. When these symptoms occur, go to the hospital to check the condition of the fetus and get the relevant treatment according to the doctor’s advice. The main symptoms of pre-eclampsia miscarriage manifest themselves. Generally, the main manifestation of pre-eclampsia miscarriage is a small amount of vaginal bleeding after pregnancy, which can be bright red, pink or dark brown in color, depending on the amount of bleeding and the time it accumulates in the vagina. Sometimes it is accompanied by slight lower abdominal pain, fetal movement with a downward sensation, backache and abdominal distension. 3. Can early pregnancy vaginal examination cause miscarriage? In normal pregnancy, vaginal examination of early pregnancy will not cause miscarriage, but it is better not to do vaginal examination for the time being for pregnant women with pre-miscarriage or habitual miscarriage. 4.What should I do if I have a fever during pregnancy? First of all, find the cause of the fever and eliminate it. Drink more water and eat highly nutritious and easily digestible food. When the body temperature is lower than 38,5 degrees Celsius and there is no obvious discomfort, you can take physical methods to lower the temperature, such as: wiping with warm water, antipyretic drugs should be used under the guidance of a doctor to avoid endangering the fetus. For fever caused by the common cold, the prognosis should be very good for both the mother and the fetus. 5.Why should pregnant women avoid contact with pets? Because pets such as cats and dogs may transmit a parasite that is harmful to both mother and child – Toxoplasma gondii. The majority of normal people infected with Toxoplasma gondii have no symptoms or very mild symptoms and can heal themselves; however, toxoplasmosis can be transmitted to the fetus by the mother, causing miscarriage, stillbirth, or after birth, eye, brain and liver lesions and malformations. 6.What should you do if you are constipated during pregnancy? Eat more fiber-rich food, eat more fruits, develop the habit of regular bowel movements, drink a glass of plain water every morning on an empty stomach, and take some mild laxative drugs or topical drugs under the guidance of a doctor in severe cases. The use of laxatives to prevent miscarriage is strictly prohibited. 7.What is the appropriate weight gain throughout pregnancy? Weight gain varies greatly among individuals, but generally the weight gain is about 12 or 5 kg throughout pregnancy, and the amount of weight gain is related to the fatness of pregnancy. People who are thinner than the standard weight before pregnancy should gain 16-20kg during pregnancy, and people who are fatter than the standard weight should gain 8kg during pregnancy. The weight gain is not obvious in early pregnancy. The weight gain should be too fast or too slow to come to the hospital in time to find out the reason, so as not to affect the development of the fetus and the mother’s health. 8.Why should pregnant women pay attention to calcium supplementation? Since the calcium needed for fetal growth and development is constantly requested from the mother through the placenta, the need for calcium increases during pregnancy. An adult woman needs 600mg of calcium per day, and after the middle of pregnancy, pregnant women should take in 500-600mg more calcium per day. If calcium is deficient, it will make pregnant women feel back pain, calf cramps, leg and foot convulsions, and affect the development of the fetus; serious calcium deficiency can cause congenital rickets in infants. So pregnant women in the diet must eat some high calcium food, such as milk, soy products, sesame, cabbage, shrimp, kelp, carrots, etc.. 9.Do you know how to count fetal movements? In order to make you and your baby safe, in the middle of pregnancy you must learn to count the fetal movements, so that you can keep abreast of the situation of the fetus in the uterus. The specific method: after 30 weeks of pregnancy, half an hour after breakfast, lunch and dinner, in the left lateral position to count fetal movements for one hour, the three fetal movement count will be added up and multiplied by 4, that is, the number of fetal movements in 12 hours. The normal number is more than 30 times. 10.What should I do if I have anemia during pregnancy? Women tend to be anemic, and they are more likely to become anemic during pregnancy due to increased blood thinning and consumption. When pregnant women have anemia, it will affect the growth and development of the fetus, and the fetus will be delayed in intrauterine development and may have low birth weight after birth; pregnant women with severe anemia may have premature birth, stillbirth, stillbirth, neonatal asphyxia and postpartum hemorrhage. Therefore, once anemia is detected, it should be treated promptly and eat more iron-rich foods in the diet, such as animal liver and soybeans, beef, eggs, purple cabbage, kelp, fava beans, celery, glutinous rice, etc. In addition, attention should be paid to the intake of vegetables rich in vitamin C to promote the absorption of iron in food and, if necessary, iron supplements to prevent and treat anemia. 11.Do you know what is meant by high-risk pregnancy? This includes the following: (1) Pregnant women younger than 16 years old or older than 35 years old, short stature, underweight or overweight. (2) A history of abnormalities in this pregnancy, such as a history of preterm abortion, viral infection, exposure to toxic substances, etc. (3) History of abnormal delivery such as: miscarriage, abnormal fetus, stillbirth, obstructed labor and gestational hypertension, etc. (4) Pregnant women with other comorbidities, such as hypertension, heart disease and diabetes. High-risk pregnancies are not scary, as long as the pregnant woman works closely with the obstetrician most pregnant women can safely survive the pregnancy and delivery period.
