Pregnant mother After pregnancy, we can see that the biggest change is the belly . Before pregnancy, the belly is very flat, but after pregnancy, the belly gets bigger little by little. Until it becomes round and round, it will gradually become smaller after the baby is born. However, during pregnancy, different pregnant mothers seem to have very different belly sizes. Some have been very pregnant very early, and some have to look carefully at four or five months of pregnancy.
When does pregnancy start to show up?
Let’s first look at the changes in the uterus:
▶Before pregnancy:Before pregnancy, the uterus is in the pelvic cavity in an inverted triangle shape. This inverted triangle is about 7cm long~ 8cm, width is about 4cm~5cm, thickness is about 2cm~3cm, and weighs about 50 grams. , almost the size of an egg. The current uterus is in the pelvic cavity, and can’t touch under normal circumstances.
▶1 month of pregnancy:It is said that one month of pregnancy, but 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 we are calculating pregnancy In one month, the fertilized egg has only just returned to the uterus for a week or two, in other words, it has only been implanted for a few days.
At this time uterus changes little, basically no different from before pregnancy , but the uterus is still in the pelvic cavity, there is no change from the outside. And for some pregnant mothers who conceive relatively late, if they are tested with an early pregnancy test strip during a month of pregnancy, they may not be able to detect that they are pregnant, unless it is a blood test.
▶2 months of pregnancy:At the second month of pregnancy, the uterus has begun to grow slowly, and the speed is very fast. At this time, the volume of The uterus has become twice that of the first month of pregnancy. . But the uterus is still in the pelvic cavity at this time. Although it has doubled in size, the uterus only obtains its position by compressing the bladder in front and the rectum in the back, so we still can't touch the uterus at this time and look outside. There is still no change.
▶3 months of pregnancy: The uterus is now bigger. The uterus is now about three times as large as before pregnancy. , the fetus is full of the entire uterus, and gradually increases with the fetus. The pubic symphysis has touched the bottom of the palace.
But in general, the uterus is still in the pelvic cavity at this time, and non-professionals still cannot touch it by themselves. Generally speaking, it is not so obvious at this time that you are pregnant.
▶4 months of pregnancy:The uterus is getting bigger and bigger, and the pelvic cavity can no longer fit it, so The uterus will grow out of the pelvis and grow into the abdominal cavity, At this time the uterus It is the same size as the head of a small fetus. The fundus of the uterus is about from the midline of the pubic bones to the middle of the belly button. If you look closely, there will be obvious marks below the belly button. Pregnant mothers can be under the belly button, that is, between the pubic bone and the belly button. The position touched my uterus, probably is 8--10cm below the belly button.
Even if it looks from the outside, it can already be seen that the belly is protruding, that is to say, it has begun to show off.
▶5 months of pregnancy:At this time, the uterus has become larger and larger. In the abdominal cavity, the enlargement of the uterus causes the belly to bulge outwards, and it becomes more and more obvious to see the protruding lower abdomen .
According to the changes in the size of the uterus, in the first trimester of pregnancy, the uterus is still in the pelvic cavity. Even though has enlarged, there is a pelvic "guard" that we can’t even touch. , Let alone see Xianhuai . After four months of pregnancy, the uterus will grow out of the pelvic cavity. As the uterus enlarges, it will continue to open the abdomen, so you will see the belly more and more.The bigger it is, that is, it took four months before it began to show off. This is not exactly what we often hear "說三不實四", it is really image and appropriate.
Is it normal to be pregnant after a month or so?
According to the above, is one month pregnant, the uterus is not very different from before pregnancy , even when it is two months pregnant, the uterus only doubled, which is 100克约, and the uterus is still in the pelvic cavity at this time. Normally, it will not show pregnancy. If it is more than one month pregnant, it should be said that it is abnormal.
One month after pregnancy, the most likely possibility is ~ fat . Many pregnant mothers are very happy after knowing that they are pregnant, and their families are also very happy and nervous. Based on "one person" The principle of "eat two people to make up " is to allow pregnant mothers to keep eating. After all, some pregnant mothers will have better appetites after pregnancy, but this time the fetus does not need much nutrition, so pregnant mothers are very It’s easy to gain weight, and I feel visceral. In fact, it is only because the fat on the abdomen is thickened and .
In fact, many people have this illusion. Lazy mothers are no exception. Although they also have morning sickness when pregnant with a second treasure, they usually eat a lot of things (mainly those sour and sour). Spicy things are not taboo), so I felt very pregnant about two months of pregnancy. At that time, I was wondering if the doctor would check me wrong. In fact, it is twins. It turns out that this is fat. That's it.
Finally, it is recommended that pregnant mothers, in the first three months of pregnancy, the main development goal of the fetus is neurological differentiation, and there is not much nutritional demand, so there is no need to do too much in the first three months of To increase the nutrition , otherwise, it is easy to overnutrition, the fetus does not grow very much, and the flesh grows a circle first.
