At 6 weeks post-conception, the fetus looks like a little blob - the spinal column has started to stand out and you might make out the eye sockets starting to fold back in. Otherwise, it looks like any vertebrate fetus and is not visually identifiable as human.
Yes. The youngest fetus saved was 21 weeks, 6 days.
It means that the egg was fertilized 6 weeks ago
Three months
Nothing. You wait for the fetus to pass (like a period).
A fetus is generally not visible on ultrasound until about 5-6 weeks of pregnancy. At 3 weeks, the embryo is very small and not typically detectable on ultrasound.
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.
Nerves begin to develop in a fetus during the first trimester of pregnancy, around 5-6 weeks gestation.
36 weeks
Everyone has a different opinion on this. Some people consider a fetus to be a baby from the moment of conception. Others consider the fetus to be a baby roughly 10 days after conception at implantation, where the fertilised egg implants in the lining of the womb. Other consider the fetus to be a baby at around 6 weeks, when there is a visible heart beat. Some consider the fetus to be a baby at around 16 weeks when you can start to feel the first movements. Others don't consider the fetus to be a baby until the abortion time limit has passed, so around 20-24 weeks. Some only consider the fetus to be a baby once he or she is born. All of the above information is correct but leaves out one crucial medical fact. Which is that of the stages of Human Development. So, in terms of human development an embryo is not a fetus, like a fetus is not a baby, like a baby is not a toddler, like a toddler is not a young adult... etc. Basically if you find the definition of Embryo it is: a developing human from conception to 8 weeks. The definition of Fetus is: a developing human from 8 weeks to birth. Then you enter the neonate, infant, toddler, play age...etc.etc. stages. Those are the Stages Of Human Development. So... when Pro-choice advocates say, "it's not a baby!" They actually are correct. And when Anti-abortion advocates say, "you are killing a developing human being" They are actually correct as well. The unborn humans are in their own stages of human development. And, the fetus is not a baby yet... just like a baby is not a toddler yet... but all humans are in their own stages of human development. Therefore, I will add this: currently, it is legal to end the life of the developing human when they are in pre-viable developmental stages in utero.
If you mean intentionally, you have to abort. If you are asking why women do, over 50% are thought to be chromosomal abnormalities in the fetus.

Around the 6 weeks point of pregnancy. However not all Dr's will tell you what it is unless you ask.
