It's bizarre and has been largely slammed I think. Abstaining in case you MIGHT be pregnant?
.
I can see the logic of it being very good ADVICE for people who are actually trying to get pregnant, as there will be that overlap between getting pregnant and knowing about it, but for people who aren't even trying? Are on birth control? Have husbands with their tubes snipped
? Even if it wasn't horrendously controlling... it doesn't even make sense.
