The chicken egg you eat is not the chicken . It requires time (and right conditions) to become one. A fertilized woman's egg also needs time to become a baby. After certain time it will not be a fetus anymore and the woman will carry the baby instead. Thats what people see when they have ultrasound scan at these later stages , their baby with full set of organs move in their body.
So its a sensitive point while discussing abortion. At first stage there is not a baby yet, fertilized or not you are sacrifiying an egg. Later you carry a baby in your body. There are two sides of the argument. First a fertilized human egg is not the human himself (yet), but later is different. If you allow parents to kill the baby because baby is disabled , then would you allow parents to make same decision when baby grows up and now five years old? Can we kill disabled kids and end their misery?
I can see what is the difference between a fertilized woman's egg and a human, but what is the difference between a baby with all the organs in their place, and a kid?
They developed a new type of ultrasound scans. They are talking about the following findings:
From 12 weeks, unborn babies can stretch, kick and leap around the womb - well before the mother can feel movement
From 18 weeks, they can open their eyes although most doctors thought eyelids were fused until 26 weeks
From 26 weeks, they appear to exhibit a whole range of typical baby behaviour and moods, including scratching, smiling, crying, hiccuping, and sucking. *
There I am posting a picture of 12 weeks old in the womb. Do you see the head, arms , legs and everything? We cant see it but she has internal organs too. Can you tell me a 5 months old baby is a baby but this is not?
