After pregnancy, we can see that the biggest change is the belly. Before pregnancy, the belly was very flat, but after pregnancy, the belly becomes bigger bit by bit. , until it becomes round and round, and then slowly becomes smaller after the baby is born. However, during pregnancy, the size of the belly of different pregnant mothers varies greatly. Some pregnant women are already very pregnant very early, and some can only be seen after careful inspection at four or five months of pregnancy.
When does pregnancy usually start to show?
First, let’s take a look at the changes in the uterus: Pre-pregnancy: Before pregnancy, the uterus is in the shape of an inverted triangle in the pelvic cavity. This inverted triangle is about 7cm~8cm long, 4cm~5cm wide and about 5cm thick. 2cm~3cm, weighing about 50 grams, almost the size of an egg. The uterus now is in the pelvic cavity and cannot be touched by ourselves under normal circumstances. 1 month pregnant: It is said that you are pregnant for one month, but in fact the gestational age of the fetus is not one month. Because the pregnancy cycle is calculated from the first day of the last menstrual bleeding, so when calculating the month of pregnancy, the fertilized egg is approximately It has only been back in the womb for about a week or two, in other words, it has only been implanted for a few days.
At this time, the uterus has not changed much, and it is basically the same as before pregnancy. The uterus is still in the pelvic cavity, and there is no change from the outside. And for some pregnant mothers who conceive relatively late, if they use a pregnancy test paper to test at one month of pregnancy, they may not be able to detect pregnancy, unless it is a blood test. 2 months pregnant: When you are two months pregnant, the uterus has begun to grow slowly, and the speed is also very fast. At this time, the volume of the uterus has become twice that of one month pregnant. But at this time, the uterus is still in the pelvic cavity. Although it has doubled in size, the uterus only obtains its position by pressing on the bladder in front and the rectum in the back. Therefore, we still cannot feel the uterus at this time and cannot see it from the outside. Still no change. 3 months pregnant: The uterus is now larger. The size of the uterus is now about three times that before pregnancy. The fetus fills the entire uterus. As the fetus gradually increases, the fundus of the uterus can be touched above the pubic symphysis.
But generally speaking, the uterus is still in the pelvic cavity at this time, and non-professionals still cannot touch it by themselves. Generally speaking, it is difficult to tell that you are pregnant at this time. 4 months pregnant: The uterus is getting bigger and bigger, and the pelvic cavity can no longer accommodate it, so the uterus will grow out of the pelvis and into the abdominal cavity. At this time, the uterus is the same size as the head of a small fetus. The fundus of the uterus is roughly from the midline of the pubic bones on both sides to The middle position of the belly button. If you look carefully, there will be obvious marks below the belly button. Pregnant mothers can feel their uterus below the belly button, that is, between the pubic bone and the belly button. It is about 8-10cm below the belly button.
Even from the outside, it can be seen that the belly is protruding, which means that she is now starting to show her pregnancy. 5 months pregnant: At this time, the uterus is getting bigger and bigger. In the abdominal cavity, the enlargement of the uterus causes the belly to bulge outward, and the protruding lower abdomen becomes more and more obvious.
According to the changes in the size of the uterus, in fact, in the first three months of pregnancy, the uterus is still in the pelvic cavity. Even though it has enlarged, it is protected by the pelvic cavity, and it is difficult for us to even touch it. Get it, let alone see Xianhuai. After four months of pregnancy, the uterus will grow outside the pelvic cavity. As the uterus grows, it will continue to expand the abdomen, so you will see the belly getting bigger and bigger. That is, it will not start to show pregnancy until four months later. Isn’t it exactly a saying we often hear: “Hide three things but not four”? It’s really vivid and appropriate.
Is it normal to show pregnancy after more than one month of pregnancy?
According to the above, when you are one month pregnant, the uterus is not much different from before pregnancy. Even at two months of pregnancy, the uterus has only doubled in size, which is about 100 grams. Moreover, the uterus is still in the pelvic cavity at this time. Normally, it will not show pregnancy. It should be said that it is abnormal if pregnancy becomes obvious after more than one month of pregnancy.
The most likely possibility of showing pregnancy after more than one month of pregnancy is that you have gained weight. Many pregnant mothers are very happy after knowing that they are pregnant, and their families are also very happy and nervous. In the spirit of "One person eats two people" The principle of supplementation allows pregnant mothers to keep eating. After all, some pregnant mothers' appetite will improve after pregnancy, but the fetus does not need much nutrition at this time, so pregnant mothers can easily gain weight. , I feel pregnant, but in fact it’s just because the fat in my abdomen has thickened.
In fact, many people have this illusion, and lazy mothers are no exception. Although I also had morning sickness when I was pregnant with my second child, I usually ate a lot of food (mainly food) under the coercion and inducement of my family. Those sour and spicy things are not taboo), so I felt that I was very pregnant when I was about two months pregnant. At that time, I was still thinking that the doctor might have made a mistake in checking me. In fact, it was twins. It turned out that, This is just fat.
Finally, I would like to advise pregnant mothers that in the first three months of pregnancy, the main development goal of the fetus is neural differentiation and does not require much nutrition. Therefore, there is no need to increase nutrition too much in the first three months. Otherwise, it will be easy to be over-nourished. The fetus will not grow much, but you will grow a ring of flesh first.
