Well, not everything. They still had sex.
Why do you hate sex? Why do you want to punish women?
...What?Pointing out that sex can cause pregnancy is a statement of fact--not a preference, not a moral judgment. Don't try to act like there's no connection between sex and pregnancy and then accuse anyone who corrects you of hating sex. You don't have to hate sex to understand how pregnancy happens, guys.
