You are 10 weeks pregnant. (eight weeks after conception)
The unborn baby is now called a fetus. Though the fetus is constantly moving, you will not be able to actually feel fetal movement for several more weeks. All of the organs, muscles, and nerves are in place and beginning to function. As the hands and feet develop fingers and toes, they have lost their paddle like look. The touch pads on the fingers form and already have fingerprints.
During this week of pregnancy the crown to rump length of the fetus is 0.9 inch to 1.2 inches (22 to 30mm), weight 0.07 ounce (2gm). They are now on the way to forming their testicles or ovaries, getting ready for the next generation. Until the ninth week of fetus development, the fetal reproductive apparatus is the same one for the both sexes. The head is still large and curves into chest.
Each week your uterus grows larger with the baby growing inside it. You may begin to see your waistline growing thicker by this time. A pelvic exam will detect that your uterus has grown from it's normal, size of your fist, to a little bigger than a grapefruit.
The baby is never in the stomach. He/she is in the uterus, which is separate to the stomach. See the related link for a picture of the baby and his/her rough position at 10 weeks.
Fetal development goes on without awareness of the shape of the uterus.

normally a fetus is 5.6 cm on average
The development of a fertilized egg starts out as an embryo though after 8 weeks it is legally considered a fetus.
About 14-15 weeks into pregnancy the fetus is about 9cm long so it was conceived 12-13 weeks ago.
That sounds about right for a 10 week fetus. The size limits are between 0.9 and 1.2 inches.
Three months
For the first 8 weeks the developing human is called an embryo after that it is called a fetus.
The size of fetus is 4 to 5 mm at 5 weeks pregnancy and about half an inch or 1.25 cm at 7 weeks of pregnancy. Fetus grows by geometrical proportion with time. So you can calculate the size of fetus at 6 weeks by mathematical calculation. Say the size be X mm at six weeks. So you have 4 mm, X mm, 25 mm in the series, So X squred equals to 4*25=100. X is equal to 10. So the size of the fetus will be 10 mm at 6 weeks.
The definition of early pregnancy is known as the first trimester. The duration of the first trimester is 12 weeks, and includes conception, implantation, development of the embryo and development of the fetus.
