Around 90% of abortions in the UK are carried out in the first trimester, (before 12 weeks of pregnancy), when the fetus is about the same size as a lime and weighs less than 14 grams. Only about 1 in 1,000 are performed in the last trimester, usually for medical reasons. Most of the gruesome images of aborted fetuses that are presented by pro-life groups are exaggerated and misleading. The fetus that is growing inside the the mother’s womb isn 't considered a human being. It can’t survive alone without the nutrients from the mother, therefore it is not yet a person. Pro-choice advocates would argue that the fetus can’t express feelings, feel pain and is not physically independent from the mother therefore they are not yet considered human.
