In germany the period is currently twelve weeks. The supreme court of germany has permitted abortion during that time stating twice
(1) That the nasciturus (the embryo or foetus) is a human being after settled within the womb (11th day) and does not "become" a human being within 9 months
(2) That aborting the nasciturus ranks among the highest level interference with human rights, that being along a line with murder, homicide, and homicide on request
(3) That it does have to be permitted in cases where the mothers life or health is in severe danger, thus at a point, where one human being might even kill another human being in real life.
(4) That it does have to be permited in cases, where the birth of the child would cause the mother not to be able to live a self - responsible life, that is if severe psychic damage was to be expected following the birth (in all cases of rape), thus creating a situation equal to the one mentioned under (2).
(5) That within the first 12 weeks of pregnancy the child does not have a right to be born without the consent of the mother. That was argued as being due to the fact, that a situation as described under (4) might eventually happen to any mother if not wanting the child (which seems to be a rather weak argument to me, if you follow their argumenatiton under (1)).
