When a lady unearths she's pregnant, she and her partner frequently wish to learn what will be 

occuring to her. They want to know the way in which the fetus will 

develop in the next several months. Footage of stages of pregnancy can help them 

better understand the process.

A pregnancy lasts roughly forty weeks. This period is split into 

trimesters of roughly thirteen weeks each. Pictures of stages of pregnancy 

can be classified by the week of the pregnancy or by the trimester. Often , 

photos of stages of pregnancy will first be found by indicating the trimester of the 

pregnancy. Once that has been identified, one can then search for photos of a 

specific week.

During the first trimester, the fertilized egg develops into a fetus with recognizable human 

traits. In the first two or 3 weeks, the fertilized egg is 

known as a zygote and it floats through the fallopian tubes until it 

attaches itself to the uterus. By the third week, the zygote has gotten massive enough to 

be considered an embryo. Though larger, the embryo is still too tiny to be 

noticeable, except with high-level technology, so few photos of this stage 

should be available.

During the weeks of the 1st trimester, the embryo grows and develops the nubs that will 

become the head, the arms and the legs and it is referred to as a fetus. By the 

end of the 1st trimester, the fetus will have grown to about to of an inch. Since 

the fetus is so tiny, there'll be few recognizable details in any 

pictures.

Most of the common pictures of stages of pregnancy are done by ultrasound. Ultrasound is 

similar to sonar. A tool much like a stethoscope is 

placed on the girl's belly and sounds that can't be heard by humans are sent into 

the belly. These sounds produce signals which bounce back to a screen. The screen displays a picture that 

is very like to a black and white picture. With ultrasound, it 

is feasible to basically see the fetus as it develops.
