1 month can you tell that you are pregnant?
Just pregnant 1 month, the physical appearance has not changed much. However, your ovaries begin to secrete luteinizing hormone, your breasts become slightly hard, your nipples become darker and more sensitive, and a slight touch will cause pain. Maybe you can feel and start to have symptoms of early pregnancy, such as vomiting, aversion to greasy food, drowsiness and so on. Of course, this will not happen to everyone. However, the baby in the pregnant belly has also changed. This month's baby is still a fertilized egg, about 0.2mm long and weighing 1.505μg, which is called "embryo" or "embryo". It looks very, very small now It looks like a pine nut by B-ultrasound. There is no fetus in pregnancy 1 week, and sperm and eggs are in you and your partner respectively. The fertilized egg is formed in the third week of pregnancy and implanted in the fourth week of pregnancy. At this time, the amniotic cavity is formed, but the volume is very small. B-ultrasound still shows no signs of pregnancy. Now the fetus is very inconspicuous. The fetus is about 0.2cm long and small and soft. The fetus just implanted in the uterus still doesn't look like a "person" in appearance. His head is as big as his body and looks like a fish with four gills and a long tail. Until the end of this month, various organ prototypes began to appear one after another, and the placenta and umbilical cord began to develop. Although the baby's heart is not as big as a poppy seed, it has already started to beat.
Be pregnant for one month, can B-ultrasound tell?
Under normal circumstances, the first ultrasound examination of early pregnancy should be completed within 3 months of pregnancy. The best examination time is eight weeks of pregnancy, the main function is to determine the gestational age, whether it is intrauterine pregnancy, and check the nt thickness of the neck (only four-dimensional color Doppler ultrasound). Some research data show that the detection rate of fetal congenital stupidity can be as high as 80% by checking the thickness of nt in the neck combined with Down's screening. B-ultrasound examination in early pregnancy is not as early as possible. It is too early to get the best test results, and it is too late to detect some diseases correctly. Therefore, the B-ultrasound examination of early pregnancy is best done in the eighth week of pregnancy. Many people, even those who are not pregnant, know that after pregnancy, they need to go to the hospital for examination in time to understand the situation of the fetus, find out some bad situations in time or ensure health and safety. Generally, the examination after pregnancy usually adopts the method of B-ultrasound examination. Because only B-ultrasound can check the specific situation of the fetus. B-ultrasound was performed by Ian of Glasgow University, Scotland, UK. Professor IanDonald invented it in 1950, and it was first used for gynecological examination. Early pregnancy refers to the period from the first week to the twelfth week of pregnancy. The literal meaning of early pregnancy B-ultrasound examination is that women have early pregnancy B-ultrasound examination. Another reason is that I am used to checking early pregnancy with B-ultrasound, because B-ultrasound has its advantages. Ultrasound examination of early pregnancy is specific, accurate, simple, economical, safe and accurate, and has high clinical application value, which can be used as a routine method for early pregnancy examination.
