How to calculate the date of pregnancy

Pregnancy is a joyful thing. After pregnancy, how to accurately calculate the number of days of pregnancy is a concern for everyone. The calculation of pregnancy life is based on the first day of the woman's due date. In medicine, 28 days of pregnancy is a pregnancy month, and normal delivery can be achieved at 40 weeks of pregnancy. Therefore, if a woman wants to accurately calculate the life of pregnancy, she needs to accurately remember the time of the due date.

1. How to calculate the date of pregnancy

1. Pregnancy life calculation is the basic knowledge that every pregnant woman should master. If the pregnancy life calculation is inaccurate, it may delay the normal delivery life of the pregnant woman. Many women think that the date of pregnancy starts from the end of their menstrual period. In fact, this is a misunderstanding. Medically, the date of pregnancy starts from the first day of a woman's last menstrual period.

2. The female pregnancy cycle is divided into ten gestational months, not just natural months. Medically, 28 days of pregnancy is considered a gestational month. Under normal circumstances, a woman's pregnancy lasts for 40 weeks. If the pregnancy lasts more than 42 weeks, it is considered to be due, and if the pregnancy lasts less than 37 weeks, it is considered to be premature. Therefore, in order to accurately calculate the life of a woman's pregnancy, it is necessary to clearly remember the first day of her expected pregnancy. The due date is calculated by adding nine or subtracting three from the first day of the expected due date.

2. Common dietary issues in early pregnancy

There is no need to increase calories in the early stages of pregnancy, just consume the same amount as usual. It is very important to consume high-quality nutrients such as protein and calcium during this stage. In addition, in order to relieve morning sickness, eating more salads and drinking more juice can also help.

1. Adequate intake of high-quality nutrients:

Pregnant women need to consume 150 calories more than the 2,000 calories an adult woman needs a day. The extra calories are equivalent to half a bowl of rice; the key is that the nutrients in the food should be balanced, so that it can be considered a good diet. Protein intake needs to be increased to 75 grams, and you need to pay attention to it every day. Protein must be consumed from the early to the middle and late stages of pregnancy, because the growth and development of the fetus, embryo, uterus, breasts, etc. require a lot of protein. If you are a vegetarian, you must find a way to supplement it.

2. Nutritional precautions to relieve morning sickness:

When morning sickness begins, digestion becomes worse and you can eat foods that can stimulate your appetite, but don't eat too much at one time. It is better to eat small and frequent meals. Especially before waking up or on an empty stomach, morning sickness will be more severe, so don't be on an empty stomach, eat some simple cookies or bread. Afraid of smelling the food, afraid of getting close to the food, cold food will have less odor than hot food and is easier to pass through. A diet mainly consists of foods with light and sour flavors, such as cold water tofu, cold noodles, cold skin, fruit salad, etc. Even if morning sickness is severe, you can eat them without pressure. If you drink too much water, your gastrointestinal function will be weakened and morning sickness will be more severe, so it is best to drink a small amount of cold water or use a little ice to quench your thirst.
