40 days pregnant belly bulging

In the case of first pregnancy, many people know that it is necessary to supplement a lot to improve the nutrition of pregnant women. Only in this way can the fetus get better nutrition and better growth. Although it is necessary to supplement nutrients, you should not blindly follow the trend. So why does the belly of a newly pregnant woman grow larger? Why is the belly so big at 40 days of pregnancy?

40 days pregnant belly big

It is usually not visible during the first three months of pregnancy. Generally, after four months, the fundus of the uterus can be higher than the coordination of the metatarsals. It is recommended to go to the hospital outpatient department for color Doppler ultrasound examination. Generally, it is because the clothes you wear during pregnancy are looser, which relieves pressure on your lower abdomen and makes you feel fat. Generally, during one or two months of pregnancy, the fetus is about the size of a grape, and the uterus it is attached to is about the size of an egg. It is difficult to tell that you are pregnant from the outside. Around the fourth month of pregnancy, the fetus is the size of a tomato. The uterus also begins to rise above the ischial tuberosity as the fetus grows. By the fifth month of pregnancy, the fetus has already grown to the size of a grapefruit, and the expectant mother's abdomen will be more noticeable. However, generally speaking, the first pregnancy will show later than the second pregnancy. Often some pregnant women feel that their abdomen is very big soon after they become pregnant. Most of them are caused by the following reasons. In the early stages of pregnancy, if you notice a noticeable enlargement of your abdomen, it may be because the expectant mother has gained weight, and fat has accumulated in the abdomen, making the belly thick.

Therefore, here is a reminder that nutritional supplements are indeed necessary during pregnancy, but in moderation. If you blindly follow the trend of dietary supplements, it will always make pregnant mothers gain weight too quickly, which is actually very bad for the fetus and themselves. In the early stages of pregnancy, the hormone metabolism of the expectant mother's body will change, and the luteinizing hormone will gradually increase, resulting in a decrease in gastrointestinal motility and a worse ability to excrete acid in the stomach. Therefore, expectant mothers are very prone to bloating and constipation at this time. This is also the key reason why the abdomen is too large in early pregnancy. Under normal circumstances, if you are pregnant with twins, the expectant mother's abdomen will be larger than that of a single baby in the early stages of pregnancy. It can be said that rapid uterine growth in early pregnancy is one of the symptoms of twin pregnancy. If you find that you are 2 months pregnant and your abdomen is larger than the normal size for this month of pregnancy, you can go to the hospital for a physical examination to diagnose whether you are pregnant with twins.

Pregnancy with twins

The birth of twin babies is caused by some criteria. A woman ovulates two eggs during an ovulation cycle. These two eggs are fertilized to produce two sperm-egg combinations, which then grow into two fetuses. Generally speaking, women produce one egg cell every month, while men produce thousands of sperm. These sperm have already passed the level of testing. Ultimately, only one male sperm can successfully fuse with the egg cell in the uterus, producing the sperm-egg combination that creates life. Therefore, most people conceived an only child. However, there are some special situations: if a sperm and egg combination breaks down into two or more sperm and egg combinations during development, twin babies or twins will appear. This condition is medically known as identical twins. The physical characteristics of identical twins are very similar, and some parents cannot clearly distinguish them. If the ovaries produce two eggs and these two eggs fuse with the sperm in the uterus, two sperm-egg fertilizations will be produced. They have independent embryos, each of which completes growth and development to produce an individual. These are called fraternal twins. Fraternal twins have very different physical characteristics. Boy and girl twins are typical fraternal twins.
