Why are you pregnant after four months?

There are often such jokes. When a woman says she is pregnant, people around her will be puzzled and say, look at your stomach. What does it look like to be pregnant? When this happens, it is not obvious that the spouse will add "Do you want to go to the hospital again to check if you are really pregnant?". Then why are you still pregnant for four months?

Why didn't you feel it for four months? Generally speaking, your stomach doesn't increase obviously in the first two months of pregnancy, and it gradually increases in the third to fourth months of pregnancy. Different expectant mothers will also have differences due to many factors such as physical fitness and diet.

In the first three months of pregnancy, the pregnant woman's abdominal protrusion is not obvious, on the one hand, because the fetus is not fully developed, on the other hand, because the pregnant woman has a strong pregnancy reaction, which leads to weak body, loss of appetite, loss of appetite, and naturally the belly enlargement is not obvious. By the fourth month of pregnancy, the pregnant woman's stomach began to get bigger, with a uterine height of 16~20.5cm and an abdominal circumference of 76~89cm. Before delivery, the height of uterus reached 32.0-38.5cm and the abdominal circumference was 89- 100 cm.

However, due to various reasons such as pregnant women's physique and eating habits, there are differences in fetal development. Some pregnant women's stomachs become obviously bigger in the third month of pregnancy, while some pregnant women's stomachs are still not obvious when they are pregnant for seven or eight months. Experts say that there will be differences in stomach size during pregnancy, as long as the fetal index is greater than normal. Pregnant women are advised to have a pregnancy check-up on time. If you have irregular vaginal bleeding, fever, dizziness, fatigue, severe vomiting and other discomfort during pregnancy, you should go to the hospital as soon as possible.

Nutrition that needs to be supplemented during pregnancy If you are in the first trimester, the nutritional demand during this period is characterized by low calorie demand, that is, the amount of food is not very high, as long as you have a balanced diet, ensure the intake of high-quality protein and supplement a small amount of folic acid. If the reaction in the first trimester is very serious and you eat less, and it is difficult to guarantee calories and various nutrients, you can choose some pregnant women's nutrition products such as milk powder or multivitamins and mineral supplements. Generally speaking, pregnant women's milk powder is fortified with vitamins and minerals, but it is usually high in calories. If your daily diet is normal, you don't need to drink more cups of pregnant women's milk powder, otherwise it will easily lead to excessive calories.

In the second and third trimester, the demand for calories and some vitamins and minerals increases. For example, the recommended calcium requirement standard in China is 65,438+0,000 mg per day in the second trimester (4-6 months) and 65,438+0,500 mg per day in the third trimester. An obvious deficiency of China population's dietary structure is that dairy products are consumed less, and many pregnant women seldom drink milk, or even don't drink milk before pregnancy. Dairy products are one of the most important sources of calcium, so the reserves of calcium will be insufficient. Therefore, when choosing nutritional products for pregnant women, in addition to milk and its dairy products, calcium can also be supplemented appropriately. In order to promote the absorption of calcium, you can bask in the sun more or supplement vitamin D preparation.
