So you allow for the plan 'B' pill, perhaps, but prohibit most abortions. Say a woman doesn't suspect she's pregnant until she's a week late. That puts the pregnancy at five weeks, which only gives the woman one week to confirm the pregnancy, decide what to do, find a clinic, find the money to pay the clinic (if it's not covered under some form of health insurance), get there (which can be a task in itself if she's in a rural area or has to come in from another jurisdiction), and actually obtain the abortion.
If she has an irregular menstrual cycle, she might not even realize she's pregnant until after the 6 weeks have passed.
Does this sound reasonable?
A fetus becomes conscious at birth.
Actually, slightly after birth, when the mental and physiological changeover from fetal circulation to post-natal circulation occurs and the baby takes its first breath. Until that moment, the brain is in a suppressed state where even many normal autonomic functions don't occur. This is why fetuses don't suffocate in the womb. It's also why comparing a premature baby with a fetus of the same gestational age is something of an apples-to-oranges comparison.
