The stages of growth of the fetus are fairly well defined. At the end of the first month it has grown beyond microscopic size. After 2 months it is a little over 2.5 cm long, its face is formed, and its limbs are partly formed. By the end of the third month it is 8 cm long and weighs about 30 g; its limbs, fingers, toes, and ears are fully formed, and its sex can be distinguished.
After 4 months the fetus is about 20 cm long and weighs over 200 g. The mother can feel its movements, and usually the health care provider can hear its heartbeat. The eyebrows and eyelashes are formed, and the skin is pink and covered with fine hair called lanugo. By the fifth month the fetus's body is covered with a cheeselike substance (vernix caseosa), which serves to protect it in its watery environment. By the end of the fifth month it is 30 cm long, weighs 450 g, and has hair on its head. At the end of the sixth month it is 35 cm long and weighs 900 g, and its skin is very wrinkled.
After 7 months the fetus is 40 cm long and weighs over 1.3 kg, with more fat under its skin. In the male, the testes have descended into the scrotum. By the end of the eighth month it is 45 cm long, may weigh 2.3 kg, and has a good chance of survival if it is born at that time. At the end of 9 months, the average length of a fetus is 50 cm and the average weight is 3.2 kg. adj., adj fe´tal.

fetus/fe·tus/ (fēt´us) [L.] the developing young in the uterus, specifically the unborn offspring in the postembryonic period, in humans from nine weeks after fertilization until birth.
fe·tus, pl. fetuses (fē'tŭs, -ĕz)
fetusThe developing individual from about the eighth or tenth week of life in the womb until the time of birth. The fetus has all the recognizable external characteristics of a human being. At 10 weeks, the fetus measures about 2.5 cm from the crown of the head to the rump. The face is formed but the eyelids are fused together. The brain is in a primitive state, incapable of any meaningful form of consciousness. By 3 months, the fetus is about 5 cm long (crown to rump) and by 4 months it is about 10 cm long. In the 6th month, the fetus is up to 20 cm long and weighs up to 800 g. Survival outside the womb at this stage is unlikely. Most fetuses over 2 000 grams do well if properly managed in an INCUBATOR. From the Latin fetus , an offspring. The common spelling ‘foetus’ is incorrect and is used only by journalists who should know better.

Patient discussion about Fetus
Q. Is chicken pox dangerous to my fetus? I am pregnant and have never had chicken pox before. My daughter is 2 years old and has not had chicken pox before and hasn't been vaccinated against it either. If she does catch chicken pox can this be dangerous to me or the fetus?
i advice you also to inform yourself and build your own opinion with this link-page:
before you would like to go on with any vaccination, you should check out this very long list of links:
at the bottom you will also find links in english. vaccinations in general are very disputable/dubious and it is probably time that we learn about it.
