I think a lot of people don't even realize 6 weeks pregnant=
2 weeks from previous period/the day of the first missed period. The most generous window of time that's possible is
maybe 3 and a half weeks to get an abortion pill if you are really keeping track of your cycle and ovulation...
and that's assuming you have a perfect 28 day cycle.
I have seen retarded anime avatar users on this very website argue that women have a full 6 weeks to decide to keep a pregnancy or not, which is just, lol, you've never seen a vagina in your life have you buddy? Women don't instantly know they are pregnant, birth control can fail, guys can slip condoms off, so on.
Also, this is to say nothing of the fact that many severe congenital defects are simply not visible to doctors until at least 3 to 5 months into the pregnancy.
